Purdue Law Offices has represented diverse clients in trademark litigation in the US District Courts of Michigan and Ohio as well as in the Trademark Trial & Appeal Board ("TTAB") of the US Patent & Trademark Office.
Recent Trademark Litigation Cases include:
-Ewald v. DaimlerChrysler Corporation (US District Court, N.D. Ohio)
We represented Ewald and his RUBICON® mark and ultimately achieved a favorable settlement. It was so favorable, in fact, that we can’t disclose the terms but we are permitted to say that Mr. Ewald is very well pleased.
-N, S, & T, Inc. v. Cheung (US District Court, S.D. Ohio)
We represented the plaintiff and its MAGIC WOK® mark and obtained a permanent injunction prohibiting Mr. Cheung from using MAGIC WOK.
-Dr. Babor GmbH & Co. KG v. Barmensen Labs LLC (TTAB)
We represented the German cosmetics company Dr. Babor and its HSR® mark in an Opposition in the TTAB against Barmensen’s application to register HFR. Ultimately, the case settled on terms which permitted the registration of HFR but restricted Barmensen’s use of HFR to non-competing goods.
- AMA Management Co., Ltd. v. Dean & Deluca Resorts, LLC (TTAB)
We represented AMA Management and its Barron’s Café® mark in a successful petition to cancel Dean & Deluca’s Café Baron mark.
-Kellogg North America Company v. Principle Business Enterprises, Inc. (TTAB)
We represented Principle Business Enterprises which was seeking federal registration for its PAW PRINTS® trademark for slippers when Kellogg requested an extension of time to oppose our client’s registration of PAW PRINTS. We negotiated an agreement with Kellogg and our client’s mark is now registered.
-Principle Business Enterprises, Inc. v. Healthdyne, Inc. (US District Court, N.D. Ohio)
We represented Principle Business Enterprises and its TRANQUILITY® mark against Healthdyne which had been using Tranquility for its CPAP machines. We negotiated a co-existence agreement designed to bolster our client’s rights to its TRANQUILITY mark and ensure that no further encroachment could occur.
-E. & J. Gallo Winery v. Alliance Foods, Inc. (TTAB)
We successfully defended private labeler Alliance Foods and its three applications to register ROBERT & JAMES for a line of food and non-alcoholic beverages against three oppositions filed by Gallo based on its BARTLES & JAYMES marks. Ultimately, the oppositions were dismissed with prejudice.
-Principle Business Enterprises, Inc. v. Sears, Roebuck and Co. (TTAB)
We represented Principle Business Enterprises in its petition to cancel Sears’ registration of PET PAWS for slippers based on our client’s prior rights in PILLOW PAWS®. Sears capitulated and, in the end, assigned it's mark to our client.
