Jackson Walker Partners With Advitam IP to Secure Federal Appellate Victory for Tenax S.p.A.

On Monday, April 8, Jackson Walker secured an appellate victory in the United States Court of Appeals for the Federal Circuit on behalf of Tenax S.p.A., a world leader in the adhesive and stone sector. The Firm partnered with Michele Katz, founder of Chicago-based Advitam IP, to handle the appeal from the U.S. Patent and Trademark Office Trademark Trial and Appeal Board (TTAB).

The case arose when the appellant filed a trademark application for a mark which the TTAB found to be too confusingly similar to the client’s registered trademark of nearly 20 years. The client challenged the trademark application after it was filed in 2014. The Appeals Court summarily affirmed the Board’s findings, granting Tenax a total victory.

Jackson Walker partners John M. Jackson and Matt C. Acosta, who argued the appeal, partnered with Advitam IP on behalf of Tenax. Established in 1960, Tenax S.p.A. operates in five continents and has production sites and sales offices in Italy, the U.S., China, and Germany.
