Merck granted review of Halozyme patent claims by PTAB

The USPTO’s Patent Trial and Appeal Board instituted Merck’s (MRK) patent grant review against Halozyme’s (HALO) MDASE patents after Merck filed a Petition requesting post-grant review of claims 1-21 of U.S. Patent No. 11,952,600, according to a post to the site of the USPTO. In consideration of “the Petition, Preliminary Response, Reply, Sur-Reply, and the evidence of record, we determine that the information presented shows that it is more likely than not that Petitioner would prevail in establishing unpatentability of claims 1-4 and 8-21 of the ‘600 patent,” the board decision stated.
