MEMORANDUM OPINION

PAYNE, District Judge.

This matter is before the Court on Rambus, Inc.’s (“Rambus”) Motion in Li-mine No. 2, to Exclude Evidence or Argument that Plaintiffs Amendment of Patent Claims was Based on Stolen Ideas or was Otherwise Wrongful or Illegal (Docket No. 576). The Defendants are Infineon Technologies AG, Infineon Technologies North America Corporation, and Infineon Technologies Holding North America, Incorporated (hereinafter collectively “Infi-neon”). By way of this motion in limine, Rambus asks the Court to preclude Infi-neon from introducing evidence or presenting argument that Rambus’ amendment of its patent claims was based on ideas acquired from documents produced and discussions conducted during the process of the development of an industry standard by a standard-setting organization, the Joint Electronics Devices Engineering Council (“JEDEC”). Infineon offers that conduct as one component of its proof to show that Rambus violated the federal antitrust law, 15 U.S.C. § 2, and the California unfair trade practice statute, Cal. Bus. & Prof.Code § 17200. Relying on the decision of the United States Court of Appeals for the Federal Circuit in Kingsdown Med. Consultants, Ltd. v. Hollister, Inc., 863 F.2d 867 (Fed.Cir.1988), and its progeny, Rambus asserts that Infineon is entirely foreclosed from offering such evidence or making any such arguments. 1 For the reasons explained below, the motion in limine will be denied.

STATEMENT OF FACTS

Founded in March 1990, Rambus develops, secures patents on, and licenses technologies to companies that manufacture semiconductor memory devices. Rambus is not a manufacturing company and thus it relies on the licensing of its patent portfolio for revenue.

*682 In 1990, Rambus filed United States Patent Application Serial Number 07/510,-898 (the “898 application”) with claims directed to dynamic random access memory, or “DRAM” technology. The United States Patent and Trademark Office (“PTO”) determined that the application covered several independent inventions. Consequently, the PTO issued an eleven-way restriction requiring Rambus to elect one invention to pursue in its application. In response, Rambus filed numerous divisional and continuation applications assert-edly based on its original application. Thereafter, Rambus was awarded numerous DRAM patents. According to Ram-bus, these patents are directed to several DRAM-related technologies: Rambus DRAM (“RDRAM”), Synchronous Dynamic Random Access Memory (“SDRAM”), and Double Data Rate Synchronous Dynamic Random Access Memory (“DDR-SDRAM”). 2 Among those patents are the four patents-in-suit: United States Patent Nos. 5,954,804 (the “ ’804 patent”), 6,034,-918 (the “’918 patent”), 5,953,263 (the “’263 patent”), and 6,032,214 (the “’214 patent”). 3 These patents were issued in 1999 and 2000.

In August 2000, Rambus filed a complaint against Infineon, alleging infringement of all four of those patents. Before trial, the Court issued a Memorandum Opinion pursuant to Markman v. Westview Instruments. Inc., 52 F.3d 967 (Fed.Cir.1995) (en banc), aff'd 517 U.S. 370, 116 S.Ct. 1384, 134 L.Ed.2d 577 (1996), construing the disputed claim terms of the patents-in-suit. Thereafter, Rambus abandoned, before trial, the charge of infringement as to the ’804 patent.

Thus, at trial, Rambus proceeded against Infineon as to the ’263 patent, the ’214 patent, and the ’918 patent. During the trial, however, judgment as a matter of law (“JMOL”) was granted in Infineon’s favor respecting the alleged infringement of those patents. Consequently, a number of Infineon’s affirmative defenses and counterclaims were no longer relevant, and therefore, some were abandoned, and others were dismissed without prejudice.

Among the counterclaims that went to verdict were those for actual and constructive fraud. The fraud claims were predicated, in part, on the theory that Rambus had violated certain patent disclosure policies of JEDEC 4 during the process by which JEDEC was establishing an industry standard for SDRAMs and later DDR-SDRAMs. As part of the evidence offered in connection with its fraud claims, Infi-neon introduced evidence that Rambus attended the JEDEC meetings first to try to get its RDRAM technology adopted as an industry standard and later for the purpose of learning about the proposed DRAM standards being developed there and then using that information to amend its pending patent applications and to file continuation and divisional applications intended to produce patents that, when issued, would encompass any technology made in compliance with the JEDEC *683 SDRAM and DDR-SDRAMs standards. In other words, at trial, Infineon offered evidence that Rambus clandestinely used information that it had acquired at, and in connection with, JEDEC meetings to guide its patent prosecution so as to capture products made pursuant to the JE-DEC standard and deliberately waited until after the DRAM industry had become “locked in” to producing products that complied with the JEDEC SDRAM and DDR-SDRAM standards to announce that the patents it had thusly procured covered the JEDEC standards. 5

During closing arguments, Infineon’s counsel argued, inter alia: “If they had invented it, it would have been in the patent in the first place, but they didn’t. They stole it. They stole it from the industry standards bodies.” 6 Counsel further argued: “They [Rambus] go to ... [JEDEC] meetings, they see the presentations .... They go meet with their patent lawyer, they start amending the claims.” 7 And: “Did Rambus attend standards bodies meetings and change their patents to cover what they saw at the standards meetings? You can’t reach any other conclusion.” 8

To rebut this evidence and defuse this line of argument, Rambus proffered a jury instruction based on Kingsdown Med. Consultants, Ltd. v. Hollister, Inc., 863 F.2d 867 (Fed.Cir.1988). In particular, Rambus offered an instruction based on the following language from that case:
