PTAB Rules That Amendment Date Does Not Qualify a Patent for Post-Grant Review

Jul 27, 2016

Reading Time : 1 min

The petitioner argued that the effective filing date of the ’890 patent is the date on which the claims were amended, March 17, 2015. The PTAB stated that 35 U.S.C. § 100(i), which defines “effective filing date,” makes no provision for the effective filing date to be later than the actual filing date of the application, even if the application is later amended, and even if that later amendment lacks written description support in the original specification. Therefore, the effective filing date of the ’890 patent cannot be the date the claims were amended. The PTAB held that the effective filing date of the ’890 patent must be either the actual filing date or the date to which the patent claims priority. The PTAB declined to rule on the validity of the claim of priority to the earlier provisional application because both the actual filing date and the earlier priority date claimed are before March 16, 2013, the effective filing date required for post-grant review. As a result, the  PTAB denied the petition. 

Adebimpe v. The Johns Hopkins Univ., PGR2016-00020, (PTAB July 25, 2016).

In considering claims to a method of reducing cardiovascular events, the Federal Circuit held that the term a “clinically proven effective” amount did not render the claims patentable over the prior art. Specifically, the Federal Circuit held that the “clinically proven effective” amount, whether limiting or not, could not be used to distinguish the prior art because the claims also specified the exact amount of the drugs to be administered in the method. The Federal Circuit also rejected patentee’s evidence of unexpected results because that evidence was tied solely to the “clinically proven effective” limitation.

A magistrate judge in the District of Delaware issued a Report and Recommendation, that found the sole asserted claim was a “single means” claim and therefore invalid for lack of enablement. In reaching that conclusion, the magistrate judge rejected the patentee’s argument that the preamble of the claim disclosed a second element that satisfied the combination requirement of Section 112, paragraph 6 because the preamble simply recited a descriptor of the very apparatus that was the subject of the means-plus-function limitation in the body of the claim. The district court judge presiding over this case has scheduled a hearing to review the magistrate’s ruling.
