IMRA Suit Proceeds Against IPG
IMRA America, a world leader in the research, development, manufacturing and application of ultra-fast fiber lasers, today received a written Notice from the US Patent and Trademark Office, confirming the patentability of all claims in its US Patent 5,818,630, entitled "Single-Mode Amplifiers and Compressors Based on Multi-Mode Fibers."
In November of 2006, IMRA filed suit against IPG Photonics Corporation (IPG) in the United States District Court for the Eastern District of Michigan, for infringement of IMRA's "'630 patent." In March of 2008, IPG asked the U.S. Patent and Trademark Office to reexamine the patent, alleging that the patent is "invalid". In the meantime, the District court suspended the infringement suit pending the outcome of the reexamination proceeding.
The latest decision by the U.S. Patent and Trademark Office rejects IPG's allegations of invalidity, reconfirms the patentability of all claims in IMRA's patent, and clears the way for the infringement suit to proceed against IPG.
During the reexamination, the U.S. Patent and Trademark Office also confirmed that a series of new claims submitted by IMRA are also patentable, providing IMRA with even further patent protection.
