In April, in Intellectual Ventures II, LLC v. Sprint Spectrum, L.P., U.S. Magistrate Judge Roy S. Payne of the U.S. District Court for the Eastern District of Texas issued a Report and Recommendation that Defendants' Motion for Partial Summary Judgment that Certain Disputed References are Prior Art should be granted in part and denied in part. In particular, Judge Payne recommended that summary judgment should be denied for four references (i.e., Hwang, Liebetreu, CATT, and LG) and granted for one reference (i.e., Yang).
In arriving at his recommendation, Judge Payne noted that an important fact question in determining whether a reference qualifies as a printed publication under 35 U.S.C. § 102 is the public accessibility of the reference. Citing Jazz Pharm., Inc. v. Amneal Pharm., LLC, 895 F.3d 1347 (Fed. Cir. 2018), for the proposition that "[a] reference is considered publicly accessible if it was 'disseminated or otherwise made available to the extent that persons interested and ordinarily skilled in the subject matter or art, exercising reasonable diligence, can locate it,'" Judge Payne pointed out that several factors are used by courts to determine whether a reference was publicly accessible. Such factors include "how widely circulated the reference was, whether the reference was indexed in a manner that would have made it accessible to interested persons with a reasonable degree of effort, and whether the reference was distributed with a pledge or understanding that the contents would remain confidential"; another factor to be considered is the expertise of the target audience.
Judge Payne addressed the Yang reference first, noting that Plaintiff Intellectual Ventures did not contest the public accessibility of this reference. Judge Payne therefore concluded that the Yang reference was publicly accessible before the priority date of the asserted patents, and as a result, recommended that Defendants' Motion be granted with respect to this reference.
Judge Payne next turned to the Hwang and Liebetreu references, which the Defendants (except for Nokia) argued were submissions to the March 2004 IEEE 802.16 Working Group Session #30 meeting, were publicly accessible by at least March 15, 2004, and thus qualified as prior art to U.S. Patent No. 8,953,641. Despite Defendants' argument, however, Judge Payne determined that "fact questions remain as to whether the Hwang and Liebetreu references were publicly accessible before the relevant priority date," since "[b]oth references were filed on a website with somewhere between 4,000 to 10,000 references (by the estimate of the applicable Defendants' own witness) with the references listed primarily in chronological order." Judge Payne also noted that "the Hwang reference was withdrawn, so it likely was not discussed at the meetings, making it even more difficult for this reference to be found." Finding that "a question of fact exists as to whether these references were publicly available as it is unclear whether persons interested and ordinarily skilled in the subject matter would be able to locate these references using reasonable diligence," Judge Payne recommended that Defendants' Motion be denied with respect to the Hwang and Liebetreu references.
Finally, Judge Payne addressed the CATT and LG references, which Defendants argued were publicly accessible by at least March 31, 2006, and thus qualified as prior art to U.S. Patent Nos. 8,682,357 and 9,532,330. Finding that questions of fact remained as to the public accessibility of these references, Judge Payne recommended that Defendants' Motion also be denied with respect to the CATT and LG references. In support of this recommendation, Judge Payne noted that "[w]hile the references were distributed by email to the working group and then placed on the 3GPP server, it remains unclear whether the references were indexed in a way that would allow persons interested and ordinarily skilled in the subject matter or art, exercising reasonable diligence, to locate the two references." In response to Defendants' argument that indexing is not a prerequisite to finding that a reference qualifies as a printed publication, Judge Payne stated that "a failure to appropriately index may still create a question of fact as to whether a reference qualifies as a printed publication." Moreover, Judge Payne noted that Intellectual Ventures' expert asserted that the CATT and LG references were not publicly available, and therefore, he indicated that "this suggests that summary judgment would be inappropriate."
Judge Payne therefore recommended that Defendants' Motion for Partial Summary Judgment that Certain Disputed References are Prior Art should be denied for the Hwang, Liebetreu, CATT, and LG references, and granted for the Yang reference.
