Narrative Opinion Summary
In this case, the United States Court of Appeals for the Federal Circuit reviewed an interference proceeding between the Regents of the University of California and a consortium including the University of Iowa Research Foundation, Coley Pharmaceutical Group, Inc., and the United States, involving U.S. Patent No. 6,207,646 (the '646 patent). The patent, held by Iowa, claims a method for reducing allergic reactions using immunostimulatory nucleic acids. California sought to interfere with the '646 patent with its own application but faced a bar under 35 U.S.C. § 135(b)(1) due to the late filing of claim 205, which was materially different from earlier claims. The Board of Patent Appeals and Interferences found that claim 205 did not relate back to earlier claims filed within the statutory period and therefore was time-barred. The court affirmed the Board's decision, emphasizing that under § 135(b)(1), claims must be filed within a year of a patent's issuance unless they are not materially different from timely filed claims. The court rejected California's argument that previous claims related to claim 205 should prevent the bar, supporting the Board's statutory interpretation. It highlighted that the statute serves as a repose to protect patentees from extended exposure to interference claims. The decision maintained the integrity of the statute's purpose to provide certainty and finality in patent rights. Each party was instructed to bear its own costs, and the interpretation of § 135(b)(1) was upheld as consistent with the statutory language and precedent.
Legal Issues Addressed
Application of 35 U.S.C. § 135(b)(1) in Patent Interferencessubscribe to see similar legal issues
Application: The court upheld the Board's decision that California's claim was barred by 35 U.S.C. § 135(b)(1) because it was filed more than a year after the issuance of the '646 patent, and it was materially different from earlier claims.
Reasoning: The Board determined that California filed claim 205 more than a year after the '646 patent's issuance and ruled that unless California could demonstrate a link between claim 205 and earlier claims filed within that year, section 135(b)(1) would bar it from the interference.

Reasoning: Upon examination, the Board compared claim 205 with California's previously filed claims 202-204 and found material differences, concluding that claim 205 could not leverage the earlier filing date of those claims.
