Failure to Properly Execute Claim of Priority Determines Fate in IPR Proceeding

Jul 1, 2016

Reading Time : 1 min

Monroe was published on July 15, 1999, after the filing of the ’073 application, but before the filing of the application that led to the ’168 patent. The Board found that Monroe disclosed each claim of the ’168 patent; however, the majority of the Board’s decision focused on the priority date of the ’168 patent and whether Monroe was actually prior art. Monroe would be prior art only if the ’168 patent was not entitled to the January 12, 1998 filing date of the ’073 application. 

The Board determined that the application leading to the ’168 patent (the “’509 application”) was a continuation of an application (the “’470 application”), which was a divisional of the ’073 application. Apple contended that the claims of the ’168 patent were not entitled to the earlier filing date of the ’073 application because the ’509 application only claimed priority to the ’470 application, which had a filing date of January 3, 2003. The Board agreed. The ’509 application did not specifically indicate the relationship of all the applications in the chain; the application identified the relationship of the ’470 application to the ’509 application, but not the relationship of the ’073 application to the ’509 application. The Board explained that “[t]he burden should not be placed on the public to track down filing dates of disparate applications when ‘the inventor is the person best suited to understand the relation of his applications, and it is no hardship to require him to disclose this information.’” The Board concluded that the earliest priority date that the ’168 patent could claim was that of the ’470 patent (January 3, 2003), which makes Monroe invalidating prior art. 

Apple Inc. v. e-Watch, Inc., IPR2015-00414, Paper 34 (PTAB June 22, 2016).

The Ninth Circuit recently reversed a district court’s decision to strike a plaintiff’s trade secret claims under the Defend Trade Secrets Act (DTSA) at the discovery stage. In doing so, the Ninth Circuit made clear that under the DTSA, whether a party defined their trade secret with sufficient particularity is a question of fact that generally does not lend itself to resolution in the absence of at least some discovery. This ruling contrasts with the California Uniform Trade Secrets Act (CUTSA), which requires a party to define their trade secrets with reasonable particularity before commencing discovery.

In a recent final written decision, the PTAB determined that a reference patent was not prior art, despite the petitioner’s post‑filing attempt to correct its petition. While the petitioner argued that it intended to rely on the patent application’s earlier date of publication, both the corrected petition and the expert declaration continued to reference the issued patent rather than the published application.

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.
