What We Do

Patterson + Sheridan is a full-service intellectual property (IP) firm, offering every possible strategy to protect and enforce IP within the U.S. and abroad. Since 1996, we've successfully secured patents, trademarks, trade secrets, and other critical assets for exceptional technology innovators, ranging from start-ups to Fortune 100 companies. We are among the world's top ten writers of original U.S. patent applications and have received accolades and high rankings over the years from U.S. News, The Business Journals, Super Lawyers, and other independent IP sources. With over 33,000+ patents granted, more than 1000 trademark applications filed and extensive trial experience. This is Patterson + Sheridan.

Patent Preparation + Prosecution

We are one of the nation’s leading intellectual property and technology law firms, securing hundreds of patents every year for some of the world’s largest, most innovative companies. In the most recent rankings of the nation’s top IP law firms, we were ranked 30th for the number of patents prosecuted per year.

Trademark + Brand Protection

Your trademark is the heart of your brand. It’s an invaluable business tool and a hallmark of your marketing and branding strategies — that’s why it deserves unique attention and unyielding defense. Trust your trademarks to the team that high-profile brands around the world depend on.

Litigation + Dispute Resolution

Protection of technology is a critical business tool. Your valuable patents, trademarks, copyrights, trade secrets and other IP rights would be meaningless without the ability to successfully enforce them. If not effectively managed, however, intellectual property litigation can be needlessly time-consuming and expensive. As an intellectual property and technology law firm with former big-firm litigators, we are uniquely positioned to win cases—and to do so in a cost-efficient way.

Technology, Licensing + IP Transactions

In addition to our deep technical knowledge and effectiveness in patent and trademark preparation and prosecution, Patterson + Sheridan has the knowledge and resources to effectively manage all aspects of a company’s IP portfolio.
