Mr. Feldman has successfully represented clients in a wide spectrum of industries with a full range of intellectual property matters.

Following law school, Mr. Feldman joined the U.S. Patent and Trademarks Office (USPTO) as a junior examiner. As part of a special training program for future agency leaders, he gained insight into the daily hands-on operation of the USPTO.  Later he served in corporate patent counsel positions at General Electric Corporation and Litton Industries.

Since 1983, Mr. Feldman has practiced intellectual property law at Feldman Law Group, litigating patent, trademark, and copyright matters on behalf of a wide range of clients.   Several cases he has handled have established new precedents in U.S. intellectual property law.

One noteworthy case set a precedent on the establishment of U.S. trademark rights by foreign companies.  Feldman Law Group defended a small chain of Bronx grocery stores against the trademark infringement claims of a large South American corporation. Both companies did business under the name “Exito” (meaning “success” in Spanish).  The South American corporation (known as the “Walmart of South America”) sued the Bronx grocery stores for trademark infringement for their use of the “Exito” name.

Although the South American company had used the Exito name in South America for years and had applied for a U.S. trademark, the trademark was never used in the U.S. Feldman Law Group argued that the South American company had no U.S. trademark rights because of this lack of use and persuaded the federal court to dismiss the federal trademark claims. Feldman Law Group’s client, the Bronx grocery chain, was able to continue doing business with its long-established name. The case set a precedent establishing that foreign companies seeking to protect their trademarks in the U.S. had to show either actual or intended use of the mark.
