Honeywell Filed Three Requests

Scott Daniels | January 29, 2009

Honeywell International requested the PTO to conduct inter partes reexamination of three BorgWarner patents claiming titanium compressor wheels – U.S. Patent Nos. 6,629,556, 6,663,347, and 6,904,949.

These new requests become part of an ongoing dispute between the two companies, the centerpiece of which is a suit in the Western District of North Carolina in which Honeywell accuses BorgWarner of infringing those three patents. On March 18, 2008, Honeywell requested ex parte reexamination against the same three patents.

In the ex parte reexamination of ‘347 patent, the PTO confirmed the patentability of each claim. The other five reexaminations are still pending.

(June 11, 2009)

The trial judge extended the discovery cutoff to October 12, 2009.
