Reexamination Requests Filed the Week of June 14th

Here is this weeks  installment of Reexamination Requests from Scott M. Daniels, of Reeaxamination Alert and Practice Center Contributor…

Notable among the requests from last week is a request filed by Mylan against Pfizer for a patent covering Pfizer’s CADUET® blood pressure treatment composition, U.S. Patent No. 6,455,574.  Pfizer sued Mylan earlier this year for infringement of that patent. Also notable are three requests filed by Furuno against Honeywell patents that are the subject of a law suit between the companies.

Reexamination requests are typically reported in the Official Gazette approximately three months after filing. Such a delay in reporting requests, particularly for requests that involve copending District Court litigation, is too long. We therefore report new ex parte and inter partes reexamination requests filed electronically the previous week as they appear on the Patent Office PAIR system.  Information on concurrent litigation is also provided, where available.

Some reexamination requests are still filed by paper.  Because of the time required for the Patent Office to review such paper requests before posting on PAIR, our report may come three weeks after filing.  The information available from the Patent Office may be incomplete in a few cases because not all the reexamination request papers have yet been posted on PAIR.  There may also be gaps in the Patent Office docket numbers listed because, for any of various reasons, a reexamination request has been assigned a docket number but is not ready for posting.
