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.
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.
As a full-service technology and IP firm, we have an intimate understanding of the unique dynamics that intellectual property assets bring to corporate mergers, acquisitions and divestitures. We have advised clients in numerous complex and high-value M+A transactions, providing insight into critical issues such as exposure to patent litigation, freedom to operate, licensing and strength in key markets.
