Practice Areas
Patent preparation and prosecution in electronics, computer science, and mechanical arts, copyrights, and trademarks

Mr. Yirga focuses his practice in the areas of Intellectual Property, Patent, Copyright, and Trademark law.  Mr. Yirga has experience in preparing and prosecuting both domestic and foreign patent applications with an emphasis in the mechanical and electrical arts, drafting and negotiating licensing agreements, trademark preparation and prosecution, and PCT practice.  Mr. Yirga’s practice has also involved enforcement actions to protect clients’ intellectual property rights, including both litigation in various U.S. Federal Courts and inter partes and ex parte matters before the United States Patent and Trademark Office.  Mr. Yirga has successfully enforced patents held valid through litigation that he drafted and prosecuted to issue.

In addition to significant utility patent prosecution experience in the mechanical and electrical arts, Mr. Yirga has drafted and prosecuted numerous U.S. design patents to issue.  A few notable markets in which Mr. Yirga has procured several issued U.S. design patents include the: automotive; footwear; and electronic components industries.  Recently, Mr. Yirga argued and successfully appealed a precedential decision before the Court of Appeals for the Federal Circuit that involved three U.S. design patents, which he drafted and prosecuted.  International Seaway Trading Corp. v. Walgreens Corp., 589 F.3d 1233 (Fed. Cir. 2009) affirmed in part, vacated in part, and remanded  International Seaway Trading Corp. v. Walgreens Corp., 599 F.Supp2d 1307 (S.D.F.L. 2008). The Seaway decision changed the law involving the test used for U.S. design patent validity.
