Lights out for Lewis Hamilton in dispute with Swiss watchmaker

“In this line of work, it’s vital that we do not conflate our personal perception with that of the ‘average consumer’ — a legal concept that serves as a reference point for assessing trademark disputes”. Dehns UK Chartered Trade Mark Attorney, Alexandra Nott, discusses the recent EUIPO Board of Appeal decision which held that Lewis Hamilton is not a well-known sports personality in the EU.

Generative AI – Will large language models (LLMs) eat themselves?

Many large language models have been trained using freely available web content, whether that be from crawling the internet, or using more specialised sources of content such as databases of patents or scientific articles.  Until recently it has been relatively ensured that most of this content is essentially human-generated.  Such content has therefore served as a useful source of training data for generative AI models, with models such as ChatGPT capable of generating text that may not be immediately and easily distinguished from human-generated content.  Similar generative AI models are increasingly used for producing image and audio content.  Newer models may therefore start being trained on content that potentially includes a significant, and increasing, proportion of content that has been generated by another model.

Will a stay of UPC revocation proceedings be granted in view of a parallel opposition at the EPO?

At Dehns, we have been eagerly awaiting the outcome of the application for a stay of the Unified Patent Court (UPC) revocation proceedings between Astellas and Healios.  The Court may stay proceedings pursuant to Article 33(10) UCPA and Rule 295(a) RoP in the case that there are opposition proceedings before the EPO where “a decision in such proceedings may be expected to be given rapidly”.  Which rapidly led to the question: just what is meant by “rapidly”?  Well, we now have one answer to this question.

Dehns Engineering Associate, John Somerton, discusses the recent High Court ruling, which finds that the training and use of an artificial neural network to suggest related media files to a user (e.g. to recommend songs) is a potentially patentable invention. The ruling has lead to the UKIPO abruptly suspending its guidelines on patenting AI inventions.

Battle of the X’s: X Social Media v X Corp.

The news that X Corp. (formerly Twitter) is being sued over its use of “X” will be unsurprising to many. Indeed, such a possibility was predicted by numerous IP experts and media outlets.  My previous article (linked at the end of this article [1]) discussed Twitter’s change to X, as well as some earlier rights that could be potential conflicts for X Corp.  Whilst some of those earlier rights may still be a problem for X Corp., there is one company in particular that holds a trade mark including the letter X, which will certainly have the attention of X Corp.’s legal team.
