Comprehensive worldwide IP protection and strategies.

Katten's IP programs build foundational strength. Our approach is brand immersive and begins with understanding your company and competitive pressures. Industry-rich experience — particularly in apparel and fashion, technology, food and beverage, pharmaceuticals, and entertainment — adds practicality and common sense. From start to finish, Katten covers your IP concerns domestically and internationally in:

  • Advertising, marketing and promotions
  • Copyrights and trademarks
  • Enforcement
  • IP-asset secured financings
  • Licensing and related commercial agreements
  • Litigation
  • Patents
  • Portfolio management and counseling
  • Trademarks and trade names
  • Trade secrets
  • Transactions

Securing IP value in deals, in court and across platforms.

Trusted by corporate boardrooms as well as by the artistic forces behind them, we dig deeper than simply what the law or IP search says. Our attorneys are authorities leading the conversation as teachers in law schools and as contributors to Successful Partnering Between Inside and Outside Counsel, Managing Intellectual Property and The Licensing Journal.

Should threats arise to brands, products or services, we protect you swiftly and decisively. We obtain temporary restraining orders to shut down high-profile infringers, navigate multichannel expansion for Fortune 500 brands and secure IP essentials for emerging companies. We also vigorously defend companies against overreaching third-party claims. In the realm of deal making and financings, the influence of IP assets is growing. Katten offers practical insights and guidance in IP valuations and strategies related to:

  • Bankruptcies and restructurings
  • IP-asset secured financings
  • Mergers and acquisitions
  • Rebrandings
