Industry-specific studies are a valuable tool to understand the mindset and priorities of others in your industry. In addition, understanding trends within your industry enhances discussions about your intellectual property strategy. However, it can be time-consuming to ascertain the relevant parameters to provide meaningful statistics.

Whilst speaking at Sustainable Fuels Europe Summit 2025 (SFES) in Madrid, Jamie Barcombe shared statistics produced by the EPO on patenting in the Cleantech industry, confirming that patents are of growing importance across the industry. The EPO study, Trends in International Patent Families (IPFs) in cleantech worldwide, 1997-2021, indicates that patent filings have been gradually increasing throughout the studied time period, with almost 55,000 patent families publishing in 2021 (Fig. 1).

Generative AI has created a legal vacuum where synthetic images and deepfakes can be created and shared without consent, yet English law offers no standalone "image right" to protect individuals. With celebrities like Lisa Riley and over 80 performers demanding reform, the question is whether the UK's patchwork of intellectual property, data protection, and common law protections can adequately address this rapidly evolving threat to personal autonomy and reputation.

The UPC Court of Appeal has confirmed that the Unified Patent Court can exercise jurisdiction over European patent applications, provided they are granted before the defendant files their statement of defence. This landmark decision means patent holders may now be locked into the UPC system even before their patents are officially granted, fundamentally changing the strategic timing considerations for opting out of UPC jurisdiction.

Who Is A “Consumer?” The Supreme Court Takes Up The Video Privacy Protection Act

The Supreme Court will decide whether subscribing to any good or service from a video provider—such as a newsletter—makes someone a "consumer" under the Video Privacy Protection Act, or whether only subscriptions to audiovisual content qualify. The case involves allegations that a website disclosed a user's video-viewing history through Facebook tracking pixels after the user signed up for an online newsletter, creating a circuit split on how broadly the VPPA's consumer protections should apply.

A New York federal court ruled that Rebel Creamery intentionally copied Van Leeuwen Ice Cream's distinctive packaging, resulting in a $23.785 million disgorgement order and mandatory redesign.
