  7. Conclusion




For over a decade, the Agencies have relied on the Antitrust Guidelines for the Licensing of Intellectual Property ("Antitrust-IP Guidelines") to aid in their analysis of complex licensing practices.(1) Recognizing that intellectual property ("IP") rights are critical to a well-functioning market economy, the Agencies crystalized some fundamental principles regarding the intersection of IP and antitrust law and policy in the Antitrust-IP Guidelines. These principles include recognizing that: (1) an IP right does not necessarily create market power;(2) (2) agreements involving IP can be analyzed using the same antitrust rules applied to agreements involving any other property;(3) and (3) IP licensing is generally procompetitive.(4) The vast majority of licensing restraints "can be expected to contribute to an efficiency-enhancing integration of economic activity," by, for example, "facilitat[ing] the combination of the licensor's intellectual property with [other] complementary factors of production."(5) The Agencies therefore will evaluate such agreements pursuant to the rule of reason.(6)

During the Agencies' Hearings on Competition and Intellectual Property Law and Policy in the Knowledge-Based Economy, panelists discussed several licensing practices that have the potential to promote licensing efficiencies, including non-assertion clauses,(7) grantbacks,(8) and reach-through licensing agreements.(9) They considered when these practices might be procompetitive, under what circumstances they might be anticompetitive, and whether the Antitrust-IP Guidelines provide adequate guidance for evaluating the antitrust implications of these arrangements.(10) The panelists generally agreed that the basic principles set forth in the Antitrust-IP Guidelines are preferable to bright line, per se rules that affirmatively approve or condemn a specific licensing practice without regard to the circumstances in which it is being employed.(11) Moreover, panelists agreed that, although theories of anticompetitive licensing practices may exist, identifying such scenarios in practice requires a highly fact-specific, case-by-case analysis. Consequently, applying simple rules to broad classes of behavior can risk great inefficiency.(12) To avoid this risk, the Agencies will continue to use the flexible rule of reason to assess the competitive significance of the licensing arrangements discussed in this Chapter, evaluating a particular agreement's ability to harm or enhance competition in the factual circumstances in which it arises.(13)


According to panelists, non-assertion clauses typically provide that a contracting party will not assert patents or other IP rights against the other contracting party, even if that party were to engage in an infringing use.(14) Panelists said that such clauses are entered into for a variety of reasons, but that, as a practical matter, non-assertion clauses serve one of the same functions as a license or cross license, i.e., they permit the contracting parties to avoid costly litigation over the use of an IP right.(15) A non-assertion clause is "a convenient way for people to be able to effectively give comfort to somebody they would otherwise license," one panelist explained.(16) In this respect, panelists stated, non-assertion clauses are similar to nonexclusive, royalty-free licenses that allow the parties to allocate risk and to avoid litigation by contract.(17) Panelists observed that non-assertion clauses can appear in multilateral or bilateral agreements, and they can cover existing or potential future patents, or both.(18) Pure non-assertion clauses that do not transfer a right to use the patent, do not, by themselves, provide for the transfer of know-how, something that frequently accompanies the affirmative licensing of patent rights.(19)

  1. Efficiencies of Non-Assertion Clauses

Panelists stated that non-assertion clauses may create efficiencies akin to those created by patent licenses.(20) For example, one panelist said that non-assertion clauses tend to reduce transaction costs because they "guarantee to the licensor . . . that any intellectual property issue that exists at [the time of the license negotiation] will be surfaced by the licensee."(21) Indeed, according to this panelist, the licensee typically will benefit by, in effect, "charging" the licensor for the value of the right it is giving up--a right to assert a hidden blocking patent, for example.(22) This panelist reported that non-assertion agreements also can facilitate the sharing of information, because a licensor who is unafraid of the eventual developments of blocking patents is more likely to "provide information and details that otherwise might be used by the licensee to develop a blocking patent position."(23) The panelist asserted that such exchanges of information are procompetitive because both parties to the non-assertion agreement avoid hidden blocking patents.(24) Finally, the panelist saw an additional potential benefit if a non-assertion clause can eliminate patent hold up for the licensor's other licensees because the clause applies to the licensor and to "those who license from the licensor."(25)

  1. Competitive Concerns Regarding Non-Assertion Clauses

Panelists expressed concern over the use of broad non-assertion clauses, such as those that are unlimited in scope or duration, or are more extensive than a license. Some panelists noted that such clauses raise competitive concerns because, by limiting the ability of licensees to collect rents on their own IP, they may discourage independent innovation.(26) Another concern is that a broad non-assertion agreement between the only two participants in a market may help to maintain an illegitimate duopoly or monopoly if the participants agree not to challenge each other's questionable patents.(27)

Invalid patents impair competition,(28) and as a matter of patent policy, challenges to their validity are encouraged.(29) As the Solicitor General recently urged, "[w]hile patent licensing in general should be encouraged because it allows the efficient exploitation of technology and promotes competition and innovation, public policy strongly favors ridding the economy of invalid patents, which impede efficient licensing, hinder competition, and undermine incentives for innovation."(30) Public policy also concomitantly favors the swift resolution of patent litigation on terms not harmful to competition.(31)


A grantback is "an arrangement under which a licensee agrees to extend to the licensor of intellectual property the right to use the licensee's improvements to the licensed technology."(32) Panelists said that a grantback is similar to a non-assertion clause in that it provides the freedom to use a particular intellectual property right, but it encompasses only future improvements.(33) Panelists noted that the two arrangements are often negotiated in the same way,(34) and that their economic effects are virtually identical.(35)

According to panelists, the scope, terms, and duration of grantbacks vary.(36) One panelist stated that a grantback may give exclusive rights to use future improvements solely to the licensor, leaving none to the licensee,(37) or it may allow both parties to share those rights to the exclusion of others.(38) Conversely, panelists noted, a grantback may be nonexclusive, thus allowing one or both contracting parties to license to others the right on the improvement.(39) Grantbacks may be limited by geographic scope or territory or by field of use, a panelist explained.(40) According to one panelist, grantbacks "may not be related to the initial IP licensed."(41) For example, a research tool patent license may grant back to the licensor the rights to make a drug created with the use of the research tool patent, even though the patent claiming the drug would not infringe the research tool patent.(42) One panelist explained that like many other licensing arrangements, grantbacks may or may not be royalty-free.(43)

  1. Efficiencies of Grantbacks

The Agencies already have noted that grantbacks, particularly those that are nonexclusive, can offer efficiencies to licensees and licensors.(44) A grantback can facilitate downstream licensing because it provides a good way to value the licensed intellectual property, one panelist asserted, stating that a grantback is "a useful way for the original licensor to get some value later on [when an] initial contract may be hard to write."(45) Moreover, a nonexclusive grantback can "serve as [an] alternative[] to higher royalty rates where the nature and value of future improvements is uncertain."(46) The Agencies recognize that a grantback can foster the sharing of risk and "reward the licensor for making possible further innovation based on or informed by the licensed technology."(47) Panelists stated that, like a non-assertion clause, a grantback can also facilitate bargaining(48) and encourage information exchange by eliminating a licensor's concern that a licensee will assert a blocking patent position in the future.(49)

  1. Competitive Concerns Associated with Grantbacks

Panelists stated that the primary anticompetitive concern presented by grantbacks is their potential for adverse effects on innovation.(50) Some have expressed concern that an exclusive grantback that allows only the original licensor to reap the rewards of any follow-on invention can deter innovation because the licensee will receive none of the benefits from any future improvements it might make.(51) One panelist stated that, as in the case of a non-assertion clause, the disincentive to innovate increases if the grantback provision "is larger in scope than the forward-going license or longer in duration than the . . . license [for which the grantback is conveyed]."(52) Some have argued that grantbacks also have the potential to extend improperly a patentee's market power because "numerous improvements made by different licensees all come back to the original patentee. The patentee can then use all the improvements, not merely to obtain control of the affected technology during the life of the original patent, but often for a subsequent time as well."(53)

These potential concerns, however, must be measured against the "but for" world; that is, the Agencies must consider the amount of innovation that might have occurred in the absence of the licensing restraint.(54) As noted earlier, grantback provisions can make follow-on innovation possible. Without the security of a grantback provision, a licensor may be hesitant to share its intellectual property with others, fearing that it might be prevented from accessing and benefitting from follow-on improvements to its own technology.(55)


Reach-through licensing agreements grant the owner of a patent on an upstream research tool(56) the right to receive consideration based on sales or usage of a subsequent downstream product created with that tool.(57) For example, a reach-through licensing agreement might allow a pharmaceutical company to use a patented research tool to identify components of what becomes a marketable drug without paying royalties to the tool owner before commercialization of the product.(58) Rather, the research tool owner would opt to "reach through" and receive a royalty based on a percentage of the drug's future sales.(59) This arrangement can be particularly valuable to the contracting parties in cases in which the creator of the downstream product has only limited ability to pay or borrow funds to cover up-front licensing costs.(60) Reach-through licensing agreements may also include the ability to use future patented inventions, including the option to license the final product created using an upstream research tool.(61)

  1. Efficiencies of Reach-Through Licensing Agreements

According to panelists, reach-through licensing agreements can create efficiencies when they promote the dissemination of an upstream research tool, by, for example, creating a way to value the research tool or establish a reasonable royalty.(62) Some have reported that the initial fee for use of a patented research tool may be difficult to determine when there is no "commercial product in existence" and "the research tool owner and the tool user may have very different views about the proper economic valuation of the tool."(63) Panelists said that by allowing the research tool patent owner to accrue royalties on sales of downstream discoveries in lieu of up-front royalties, the parties are better able to assess the value of the research tool by taking into account the value of the product developed using the research tool.(64) Reach-through licensing agreements also permit the research tool owner and follow-on researchers to share innovation risks, with the research tool owner gambling that his tool will lead to the development of a commercially viable product.(65) In this way, reach-through licenses may facilitate an efficient allocation of risk when there is uncertainty regarding the value of the licensed technology.

  1. Competitive Concerns About Reach-Through Licensing Agreements

Panelists were primarily concerned that reach-through licensing agreements could impair innovation in downstream markets(66) because of "royalty stacking" by multiple research tool owners.(67) Royalty stacking occurs when royalties are owed to multiple licensors. As one panelist noted, when "one company comes in and asks for five percent, another company comes in and asks for five percent, . . . all of a sudden you're . . . giving away a hundred and twenty percent, three hundred percent of your revenues to various patents."(68) Although no rational firm would knowingly agree to give up all its profits, some have expressed concern that the cumulative royalties of all upstream holders have the potential to stifle follow-on innovation if they reach a level at which commercialization of the improvement is no longer profitable from a business perspective.(69) Thus, some fear royalty stacking may result in a "tragedy of the anticommons" whereby "people under use scarce resources because too many owners can block each other."(70) At the Hearing, the Deputy Associate General Counsel of the National Institutes of Health ("NIH") explained that NIH adopted a policy discouraging the use of reach-through royalty agreements because they may impose restrictions on the IP developed using the tool, as well as create multiple royalty obligations associated with downstream discoveries.(71)

Some have argued that reach-through licensing does not allow a patentee to capture excessive royalties and does not pose a concrete harm to innovation. As one panelist explained: "If the licensor . . . is about to propose a royalty that's going to kill the product they're not going to make any money. And most of the players in this field are sophisticated enough to understand that."(72) In any event, the inefficiencies associated with royalty stacking can occur even without the use of reach-through licensing agreements.(73) Thus, some panelists opined that reach-through licensing agreements raise no real competitive concerns unless licensors adversely affect innovation by prohibiting entry or exploitation of the upstream research tool or downstream products.(74) In addition, another panelist reported that extensive interviews of people in the biomedical industry demonstrated that the "anticommons" had not developed.(75)

Panelists also suggested that reach-through agreements could reduce incentives to challenge a potentially invalid patent or the scope of protection claimed by the patent "by specifying that payments continue even if the patent were to be found invalid or the product [is] non-infringing."(76) Other panelists asserted that the collection of royalties on a patent that is beyond its statutory term or scope could amount to an antitrust violation or patent misuse.(77) These panelists suggested that the patent misuse doctrine or antitrust law would not allow a "licensing company [to demand] royalties on the sale of a product that is not covered by [its] patent"(78) or to extend royalty payments beyond the enforceable life of the patent on the underlying research tool.(79) Other panelists disagreed. From an economics perspective, "spreading out royalties over a larger [base] and a lower rate could be better," one panelist opined, because that would suggest the licensee negotiated a lower rate.(80) From a legal perspective, another panelist remarked, reach-through royalties can be a mechanism for metering, which antitrust law has generally treated favorably because it "tends to disseminate technology [often more broadly] than a single price."(81) Indeed, in 2002 one federal trial court found no patent misuse when a reach-through licensing agreement provided for royalties based on products not covered by the patent and allowed for the collection of royalties beyond the term of the patent, because the agreement was structured for the convenience of the parties and was valued based on the patent's actual term.(82)


Panelists debated several analytical approaches for evaluating competitive concerns raised by the licensing practices discussed in this Chapter, particularly with respect to non-assertion clauses and grantbacks. One panelist, for example, advocated an assessment of likely competitive effects in both the relevant product and innovation markets.(83) Although other participants agreed that such an analysis would be desirable, they questioned whether it would always be practical.(84) Another panelist proposed the use of a market power screen, asking "do the firms entering into this agreement jointly have market power?"(85) Consideration of market structure, market power, and complementarities can, according to the panelist, lead to a correct assessment of parties' incentives for efficient rather than anticompetitive conduct or vice-versa.(86)

Panelists suggested that market power is not always easy to determine, however.(87) One participant therefore advocated applying the ancillary restraints doctrine to assess a potentially anticompetitive provision as "a heuristic kind of approach" that "establishes certain rules that are administrable and somewhat easy to understand and apply at the time you're doing an agreement."(88) Another panelist found the doctrine to be unhelpful in some cases, when there are no restrictions on the use of the technology, as is the case for a mutual or one-way non-assertion agreement.(89) Other panelists desired more definite guidance, such as specific factors to consider when structuring a licensing agreement or practices that raise "red flags" or provide "green lights."(90) Using a grantback as an example, one panelist proposed several shortcuts, inquiring whether the grantback is "beyond the duration of the license" or "relating to products that are only marginally related to the initial licensed technology" or if it is exclusive.(91) This panelist conceded, however, that defining such shortcuts would be difficult because "at this stage [we are] still looking for answers."(92) Another panelist asserted that fixed rules are not the best answer, pointing to the abandonment of the "Nine No-Nos" by the Department of Justice.(93)


The Agencies generally agree with the panelists' conclusions that fixed antitrust rules in intellectual property licensing are often difficult to articulate(94) and are not necessarily desirable.(95) To evaluate whether a particular restraint is likely to have anticompetitive effects pursuant to the rule of reason, the Agencies ask whether the restraint is likely to diminish competition in a properly defined market "among entities that would have been actual or likely potential competitors" in the absence of that restraint.(96) Pursuant to a rule of reason analysis, the Agencies consider the anticompetitive concerns and the efficiencies of the particular arrangement.(97) In general, the Agencies expect that non-assertion agreements, grantbacks, and reach-through licenses either will not raise any competitive concerns or that the efficiencies of these types of agreements will be sufficient to alleviate competitive concerns. Several factors will be particularly relevant to the Agencies' examination of these licensing practices, including (1) whether the patent holder possesses market power in the relevant market, (2) whether the practice encourages unlawful coordination among competitors, (3) whether the practice inhibits entry of other firms through the licensing regime's exclusivity or exclusion, and (4) whether the practice reduces the incentive to innovate in the future.(98)

As a threshold matter, the Agencies do "not presume that a patent, copyright, or trade secret necessarily confers market power upon its owner" because intellectual property rights are not necessarily associated with market power.(99) A patent, for example,

may create a monopoly--just as an auto manufacturer may own all of the auto production facilities--but property and monopoly usually differ. That a patent covers an "entire" idea or product no more implies monopoly than the fact that USX Corporation owns the "entire" South Works in Chicago. Frequently, indeed almost always, different patented goods and processes compete with each other and with unpatented goods and processes.(100)

For this reason, "the antitrust agencies determine whether a patent owner possesses market power by applying the same analysis that they apply to any other valuable asset, which requires the consideration of possible substitutes that might allow consumers to turn to other suppliers of a similar product or process."(101) Consistent with this approach, in Illinois Tool, the U.S. Supreme Court recently held that market power cannot be presumed based on the existence of a patent.(102) Equally important is the notion that, "[i]f a patent or other form of intellectual property does confer market power, that market power does not by itself offend the antitrust laws."(103) Market power that is "solely 'a consequence of . . . superior product, business acumen, or historic accident'" does not create competition concerns.(104) Efficiently exploiting the market power that might be associated with an intellectual property right is likely reasonable conduct under the Agencies' framework, provided that market power is legitimately obtained and maintained.(105)

Although efficient exploitation of the market power associated with an intellectual property right is likely reasonable and procompetitive activity, the licensing of intellectual property rights can involve coordination, especially if a license includes restrictions on the use of the intellectual property rights. Coordination between or among intellectual property holders on one aspect of competition may provide a means or opportunity for coordination on other aspects of competition, such as downstream price or output.(106) Sometimes competitive concerns arise not from the underlying arrangement itself, but rather from attendant restrictions that may facilitate coordination on price or other competitive variables.(107)

In addition, exclusivity could raise competitive concerns if, for example, firms agreed to limit their granting of non-assertion clauses to each other, precluding other competitors from receiving such protection from infringement suits by the parties to the agreement. An exclusive reach-through licensing agreement might also raise competitive concerns if it has a substantial impact on the ability of other competitors to innovate.(108) Of course, the Agencies recognize that exclusivity can have desirable effects on competition and innovation, by, for example, encouraging investment in the research, development, and marketing of a product created with the licensed technology.(109) Thus, when analyzing a particular license requiring exclusivity, the Agencies weigh such efficiencies against any anticompetitive effects.(110)

Finally, certain licensing practices could impede innovation. If a license includes restrictions on patents that have yet to be issued or filed, competitive concerns could arise about the arrangement's likely effect on future innovation. Scholars have expressed concern about grantbacks that require the licensee to assign all rights to improvements to the grantor, thereby potentially reducing the licensee's incentives to improve the patented technology.(111) Non-assertion clauses that are the functional equivalent of broadly worded grantbacks could raise similar concerns.

In contrast, the Agencies may find that a situation such as the "royalty stacking" generated by multiple reach-through licensing agreements does not raise antitrust concerns even when it might impede innovation. In some cases, licenses on multiple patents, each requiring payment of a royalty, are legitimately required to innovate, develop, or commercialize a new product. However, assuming no anticompetitive conduct and that the patents at issue are legitimate, the mere fact that the cumulative cost of the licenses might impede innovation is not an antitrust issue. In this context, the antitrust laws permit a single IP holder with a desirable intellectual property asset to extract as much return as the market will bear for the use of that property.(112)

Moreover, according to panelists, it is often not clear that the cost of royalties arising from reach-through licensing agreements will be excessive, such that it impedes innovation or otherwise causes competitive harm. The royalty that an upstream firm may charge for use of a patented research tool will be limited by the downstream firm's willingness to pay. That willingness will reflect the value of the patent to the downstream firm, and includes considerations such as the probability that the patent would be found invalid or unenforceable, as well as the difficulty of detecting infringement. The Agencies' rule of reason analysis, applied to particular facts, may well indicate that anticompetitive harm would not arise from a reach-through licensing agreement,(113) in which case the Agencies would not challenge the agreement.(114)


Panelists generally agreed that the various licensing practices discussed in this Chapter can provide great efficiencies to the contracting parties that would ultimately benefit consumers, but also that each licensing practice has the potential to stymie innovation and weaken competition among firms. These countervailing effects complicate an antitrust analysis, especially because procompetitive benefits and anticompetitive effects can be difficult to unravel, and may or may not be present in any individual case. Indeed, the competitive effects of certain licensing practices are not obvious--an example is the reach-through license, where the harm may not be apparent simply by examining the four corners of the agreement. Most panelists recognized that the Agencies are not in a position immediately to decipher possible procompetitive benefits and anticompetitive effects or to provide fixed rules that work efficiently in every case. Although "red flags" and "green lights" may be easy to apply, many panelists found them considerably less desirable than the Agencies' current approach based on principled economics.(115)

The Agencies will continue to apply the flexible framework set forth in the Antitrust-IP Guidelines and to evaluate each licensing practice individually with particular focus on whether it "harms competition among entities that would have been actual or likely potential competitors in a relevant market in the absence of the license."(116) The Agencies will analyze the agreements discussed in this Chapter pursuant to the rule of reason.(117)

Id. at 136 (Fromm) ("[A broad non-assertion clause] can't help but be a disincentive to the licensee, the grantor of the non-assert, to further innovate because essentially what [it has] done is [it has] eliminated the patent thicket, that's for sure."); see also id. at 137-38 (Rule) ("[Y]ou can certainly abuse a non-assert if it's way too broad and it's unconnected to the underlying licensed technology."); id. at 143 (Fromm) (stating that the proper focus is on whether the non-assertion clause is "significantly more extensive" than the scope of a license). According to panelists, although a patent thicket has the potential to impede innovation when access to certain inputs necessary for production is difficult, the elimination of a patent thicket altogether can slow innovation when no firm has the incentive to innovate by designing around an infringing patent. See, e.g., Frederick J. Telecky, Jr., Statement (Feb. 28, 2002 Hr'g R.) at 3 ("Without the need to design around, simple inertia and practicalities such as the necessity of qualifying a new product with customers can be a barrier to innovation."),

The anticompetitive concerns associated with the use of grantbacks within a patent pool are discussed in Chapter 3, Antitrust Analysis of Portfolio Cross-Licensing Agreements and Patent Pools, and are essentially the same as those noted here. Broad grantback clauses that, for example, "cover entirely unrelated technology, [cover] future as well as present patents, [or] cover non-essential as well as essential patents," may deter innovation and should, according to panelists, engender antitrust scrutiny. M. Howard Morse, Cross-Licensing and Patent Pools (Apr. 17, 2002 Hr'g R.) at 14,; see Apr. 17 Tr., Patent Pools and Cross-Licensing: When Do They Promote or Harm Competition? at 204-05 (Morse) (recognizing that Department of Justice business review letters had approved grantback provisions that were structured so as not to impede innovation),

57. FTC Innovation Report ch. 3, at III(E)(1). Although a research tool is used to develop a new product, the sale or use of the new product generally will not infringe the claims of the research tool patent. See Feb. 26, 2002 Hr'g Tr., Business Perspectives on Patents: Biotech and Pharmaceuticals (Afternoon Session) at 260 (Blackburn) ("[A research tool] is not a patent that covers the final product that is the subject of ongoing manufacture and sale."), [hereinafter Feb. 26 Tr.].

L. Rev. at 171 ("Reach-through rights allow patent holders to license and reali[z]e value on their inventions even when that value is speculative. In this respect, they encourage the dissemination of patented inventions and are likely to have a positive effect on innovation."); Mueller, 76 Wash. L.

63. Mueller, 76 Wash. L. Rev. at 16.

64. See Nov. 6 Tr. at 154-56 (Burtis) ("[P]eople [like] reach-through agreements because . . . [they are] a way to efficiently price . . . ."); Feb. 26 Tr. at 279 (Blackburn) ("I think that really reduces to a price negotiation, how much does the tool owner profit from the successful development of a product. So that allocation of risk I think is taken care of in the pricing."); see also Nielsen, 32 Fed. L. Rev. at 176 ("If an upstream invention is subsequently determined to be a foundational research tool, setting a value on it too early would deprive the patent holder of valuable income, and allow the licensee to reali[z]e a windfall gain. Reach-through rights allow the patent holder to defer decisions about the value of research tools and technologies.").

65. See, e.g., Feb. 26 Tr. at 275 (Blackburn) ("Reach-through royalties are a way to lower the up-front costs for the smaller firms and to have a risk-sharing arrangement basically with the tool owner . . . ."). But see id. at 278 (Oehler) (questioning whether "risk is truly shared" when a tool may prove valuable in early stages of research and development but the end product fails in clinical trials).

66. See, e.g., Nov. 6 Tr. at 153 (McGarey) (arguing that reach-through agreements can result in a "pile-up" of royalties that impair innovation); July 10, 2002 Hr'g Tr., Trends in Federal Circuit Jurisprudence (Morning Session) at 56-57 (Scherer) (stating that numerous upstream patents can impede downstream innovation by, among other things, attempting to collect royalties individually),; Oct. 30, 2002 Hr'g Tr., Competition, Economic, and Business Perspectives on Substantive Patent Law Issues: Non-Obviousness and Other Patentability Criteria at 175 (Stoner) (asserting that when an upstream patent manages the downstream flow of innovations it could lead to less downstream commercialization), [hereinafter Oct. 30 Tr.].

Co-Operation & Dev., Genetic Inventions, Intellectual Property Rights and Licensing Practices: Evidence and Policies 63 (2002) [hereinafter Genetic Inventions] ("The concerns evoked about reach-through royalties are that they increase royalty stacking, as multiple tests and assays are needed when developing a medicinal product[;] that they make project management more complex and the relationship to all collaborators more delicate[;] and that they are costly to negotiate.").

Reg. 72,090, 72,091 (Dec. 23, 1999), available at; Mueller, 76 Wash. L. Rev. at 7-8, 16 (discussing NIH's position). To foster access to protected research tools, for which a license on reasonable terms cannot be freely negotiated, the National Research Council of the National Academies recommends that federal research-sponsoring agencies assume liability for patent infringement arising from the use of a protected research tool by including an "authorization and consent" clause in research funding instruments.

73. If numerous complementary patents are necessary to create a new innovation and these patents are valued independently by multiple licensors, then the total royalties paid generally will be greater than they would be if all patents were controlled by a single licensor. See, e.g.,Carl Shapiro, Navigating the Patent Thicket: Cross Licenses, Patent Pools, and Standard Setting, in 1 Innovation Policy and the Economy 121, 122-23 (Adam B. Jaffe et al. eds., 2000). In economics, this problem is known as "double marginalization" and can be mitigated with the use of a patent pool. See supra Chapter 3, Antitrust Analysis of Portfolio Cross-Licensing Agreements and Patent Pools Part III.D.1.b.

See Nov. 6 Tr. at 169 (Ordover); id. at 171-72 (Rule); id. at 169-70 (McGarey) ("[NIH] certainly [does not] like reach through [licensing agreements] . . . but I don't think I can say that it's anticompetitive or it's something that the Federal Trade Commission or the Department of Justice needs to look at because . . . it's something that the marketplace takes care of, perhaps, very painfully.").

And so, it's a way for a patent owner to really extend rights that the patent system has not really given them.").
