Important privacy update.

DROP (Delete Request and Opt-out Platform) is a centralized state-run tool launched on January 1, 2026. It allows California residents to submit a single request to delete their personal data and opt out of sales across over 600 registered data brokers, with mandatory broker processing starting August 1, 2026.

Trademarks can be among a company’s most valuable assets—and one of its biggest deal risks. In fact, the global value of corporate intangible assets, including brands and trademarks, is estimated at nearly $100 trillion, highlighting the critical role IP plays in business value.

At Trademarks in Transactions and Commercial Activities: Due Diligence, Deal Risk, and Value Drivers, learn how trademark administrators help identify ownership gaps, chain-of-title issues, recordal challenges, and other risks that can impact transactions before they become costly problems.

Join moderator Tracy Arch and speakers Yann Correia and Chris Turk for practical insights into trademark due diligence, transaction readiness, and protecting brand value before and after a deal closes.

USPTO update!

Transition to Madrid e-Filing
U.S. office of origin, outbound international filings are moving from the Trademark Electronic Application System International (TEASi) to the Madrid e-Filing system:

Between July 31 and September 30: File in TEASi or Madrid e‑Filing
Beginning October 1: File all new outbound applications in Madrid e‑Filing
Madrid e-Filing is a secure filing system run by the World Intellectual Property Organization (WIPO). Through Madrid e-Filing, you can file applications for international trademark registrations based on U.S. applications or registrations, which the United States Patent and Trademark Office (USPTO) and WIPO then process. You can directly communicate with the USPTO through the system and respond to any deficiencies identified by the USPTO in the international application or irregularity notices that WIPO’s International Bureau (IB) might issue.

You need a WIPO account to use Madrid e-Filing.
