$HALO $HALO Halozyme One more reason (not mentioned in my previous post) why odds favor Halozyme's sucsess in the patent dispute: Merck would have to prevail in invalidating every single claim in every single PGR. For example in patent #600 (PGR 006) alone, there are about 21 claims in different categories. Claims 1-4, 8-10: Focus on the modified PH20 polypeptide itself, either as a base composition
• Claims 11-13: Cover genetic tools (nucleic acid, vector, host cell) for producing the polypeptide.
• Claims 14-18: Cover pharmaceutical compositions
• Claims 19-20: Describe methods of administering the compositions.
• Claim 21: Describes a method of manufacturing the polypeptide.
“If any of these remaining claims are upheld as patentable following the trial, the ’600 patent will remain valid with respect to those claims. Conversely, if all remaining claims are found unpatentable, the patent would be invalidated.”
