Dolby spun off about half its GE Licensing portfolio in deal with Dominion Harbor  

GE Licensing represented one of the great legacy portfolios in the patent market, and Dolby’s acquisition of the unit last June was the marquee transaction of 2024. Now, thousands of those patents are on the move again. 

Dolby has held onto all video coding SEPs from GE, it says. However, it is moving to maximise non-core assets through sale. Dominion Harbor has ended up with around 2,500 GE patents, approximately half the original portfolio. The rights span a wide range of areas, including 5G cellular. The monetisation firm run by David Pridham has also closed recent cellular deals with Ofinno and Shanghai Langbo.  

Elsewhere, we look at the video space, where InterDigital added rights related to streaming and Philips picked up a pair of portfolios originating in Korea.

Transactions watch is a bimonthly Sisvel Insights feature. Our aim is to help patent owners, technology users and their advisers stay abreast of patent transfers with the potential to affect the licensing landscape. It is entirely based on public records and news reports. 

The main focus is on fields of technology subject to significant standardisation – including mobile communications, wireless networking and multimedia – but we also highlight deals in other technology areas that catch our attention. 

Discussion of the technology covered by various patents is based solely on keywords in the patent titles – readers can review the patents in full via the linked transaction documents.
