Massachusetts Institute of Technology and Versitech Limited patent, licensed exclusively by Arch, is maintained without amendment as prior lower court decision is affirmed.

FRAMINGHAM, Mass., Dec. 04, 2018 (GLOBE NEWSWIRE) -- Arch Therapeutics, Inc. (OTCQB: ARTH) ("Arch" or the "Company"), developer of novel liquid, gel and solid hemostatic and wound care devices, is pleased to announce that the Japanese Intellectual Property High Court has favorably ruled to affirm the prior trial decision and maintain without any amendments Japanese patent number 5204646 (‘646). This patent is part of the intellectual property estate that Arch has licensed globally and exclusively from the Massachusetts Institute of Technology and Versitech Limited (“MIT”).

The ‘646 patent was challenged in a Japanese court by an opponent. Previously, a Japanese Court issued a decision in our favor to maintain the patent in its entirety. The opponent appealed the decision. On October 30, 2018, the Japanese Intellectual Property High Court affirmed the lower court decision to maintain the patent in its entirety. The opponent has one remaining right to appeal this decision. 

Chief Executive Officer, Terrence W. Norchi, MD, said, “We value both our licensed and internally developed intellectual property. We appreciate the court’s reaffirmation of the patent rights and reserve the right to protect and defend our technology.”

As previously announced, Arch filed a 510(k) premarket notification for AC5™ Topical Gel in the United States in the third calendar quarter of 2018. The submission is under review. Further, Arch filed a CE mark for AC5™ Topical Hemostat during the fourth calendar quarter of 2018.

Norchi added, “These next weeks, months, and quarters are important to Arch as we continue to develop our products for commercialization in the US and Europe.”
