Intellectual Property
Back to Practice Areas

Many of our clients’ business fortunes depend in large part on their ability to protect their intellectual property, or to defend against others’ allegations of misuse of intellectual property. These clients turn to Greene Espel’s attorneys where these most important assets are at stake. From burgeoning high-tech companies to large international manufacturers, our clients have entrusted us with responsibility for major disputes relating to trade secrets, patents, trademarks, and copyrights. Our attorneys have litigated, tried, and defended on appeal cases in these areas across the United States, often when tens of millions of dollars or more were at risk. Here are a few examples of what our attorneys have done:

Trade Secrets

  • Helped a national lending institution protect trade secrets associated with its lending and compliance practices after our investigation showed that a former employee had stolen trade secrets and brought them to a competitor.
  • Defended the inventor of a fabric treatment technology in trade secret action brought by a competitor, obtaining an early dismissal.
  • Represented an alloy wheel manufacturer in a trade secret case against a competitor, obtaining a favorable resolution following the court’s denial of the competitor’s summary judgment motion.


  • Pursued infringement litigation, tried cases, and obtained favorable results on behalf of numerous clients as plaintiffs and defendants in cases involving patented technology relating to software, databases, computer equipment, industrial equipment, color transfer, electrical circuits, and mechanical operations.
  • Obtained dismissal of all patent claims against our client, an international medical device manufacturer, in a multi-party patent infringement suit.
  • Represented clients in actions before the International Trade Commission to prohibit importation into the United States of products that infringed our clients’ patents.
  • Regularly represent a Fortune 100 company in disputes with patent licensees.
  • Represented manufacturers of products as diverse as perfume and printer ribbons in actions against the distributors of inexpensive and infringing knock-offs.


  • Resisted a motion for preliminary injunction, and later obtained summary judgment, on trademark claims against an international animal feed producer.
  • Obtained summary judgment on fraud claims relating to trademark rights that our client’s adversary believed were worth more than $18 million.
  • Represented a telecommunications corporation in the appeal of a trademark dispute concerning a competitor’s logo.
  • Resolved a trademark infringement claim brought on behalf of a national sportswear manufacturer.
  • Represented an Internet start-up company in a domain name dispute involving the Anticybersquatting Consumer Protection Act and the Federal Trademark Dilution Act of 1995.
  • Represented an international religious organization in a copyright and trademark dispute against a rival church.
  • Represented the IP arm of a national professional sports league in protecting its trademarks throughout the United States.


  • Helped The Kingsmen recover ownership of their musical recordings, including the roll-and-rock classic “Louie Louie.” This suit, which reached the United States Supreme Court, involved both common law copyright and contractual issues.
  • Represented an architectural design firm in connection with various copyright and trade secret disputes.
