Pennsylvania Company Files Patent Infringement Suit

N.A. Water Systems, LLC (“NAWS”) filed suit for patent infringement in the Western District Court of Pennsylvania on April 14, 2010.

The complaint alleges that Aquatech International Corporation and Debasish Mukhopadhyay infringe NAWS’s rights as an exclusive licensee of U.S. Patent No. 5,250,185 entitled “Reducing Aqueous Boron Concentrations with Reverse Osmosis Membranes Operating at a High pH.” NAWS seeks various declarations that:

1. NAWS’s process known as OPUS does not infringe U.S. Patent Nos. 5,925,255 and 6,537,456 owned by Mukhopadhyay;
2. Any actions by NAWS relating to promoting the OPUS process do not contribute to or induce infringement of Mukhopadhyay’s above-referenced patents; and
3. Mukhopadhyay’s above-referenced patents are invalid and unenforceable.

An answer has not yet been filed.
