Largest Patent Buyers in 2025 and What Their Acquisitions Signal

In February 2025, Peninsula Technologies acquired 364 patents from Ofinno, and in April 2025, Dish Wireless was sued. With just 63 days, the acquisition-to-enforcement window of licensing companies has shrunk from years to weeks, and the need to be on the toes with these acquisition activities has never been higher.

Peninsula Technology’s purchase was among the largest single-portfolio transfers of 2025, followed by FEC IP LLC’s purchase of 232 assets from Funai Electric Co. Considering the top 3 transactions by patent licensing companies, they alone account for more than 1,100 transferred assets. 

That concentration is important because the broader litigation market is trending in the same direction. RPX reports that patent licensing companies added 2,236 defendants to patent litigation campaigns in 2025, an increase of 18.7% compared to 2024. 

What makes these licensing companies distinct is not just that they buy aggressively; it’s how quickly buying turns into action when the portfolio aligns with deployed systems and products. 

This article examines the early risk window by identifying the patent-licensing companies that acquired the largest portfolios in 2025. By connecting historical enforcement data, targeted technology domains, and publicly known defendants, the article highlights which industries and product categories are most likely to be approached next.

15 Patent Buyers Most Likely to Set Licensing Terms in 2026

The fifteen most active patent licensing entities in 2025 collectively acquired 2,236 patent assets, primarily from companies operating in telecommunications, networking, semiconductors, and consumer electronics.

These acquisitions were not evenly distributed. They were concentrated among licensing entities with documented enforcement histories and focused on technology domains that have repeatedly surfaced in past litigation, including wireless infrastructure, packet processing, memory systems, and software-driven control functions.

Apogee Networks emerged as the single largest acquirer, securing the Langbo Communication portfolio, which industry observers identify as comprising 4G and 5G cellular technologies. The transaction, reportedly involving Fortress Investment Group’s backing, positions Apogee as a significant holder of wireless standard-essential patents.

Second on the list, Peninsula Technologies’ acquisition of 364 patents from Ofinno attracted particular attention within the IP transactions community. Dominion Harbor, Peninsula’s parent entity, characterised the portfolio as standards-essential communications assets spanning wireless handset and base station technologies, with particular concentration in 5G innovations including power control, carrier aggregation, network slicing, and dual connectivity systems. 

The portfolio’s priority dates, with 90% originating from 2015 or later, suggest coverage of relatively recent technological implementations currently deployed in commercial networks.

Palisade Technologies itself executed a 112-patent acquisition split between Fortinet Inc (56 patents), SanDisk Technologies (48 patents), and Alaxala Networks Corporation (8 patents). The entity was involved in a lawsuit against Micron Technology in October 2024, alleging infringement across DRAM, NAND Flash, and NOR Flash memory products. The case reached a settlement within months, exemplifying the licensing-focused enforcement strategy employed by many of these entities.

Although the asserted patents were not the same assets acquired in these transactions, the technologies at issue in the litigation align closely with the core technical areas of the companies from which Palisade sourced its patents.

Historical enforcement patterns

Past litigation activity by several of the most active buyers provides a clear reference for how the litigation phase in 2026 is likely to unfold.

Intellectual Ventures and its affiliated entities have maintained the most substantial litigation presence. According to Unified Patents data, Jeffrey M. Gross and Intellectual Ventures collectively led 2023 in suits filed by patent licensing entities, with 226 cases initiated. This sustained high-volume approach to enforcement has targeted financial services institutions, telecommunications providers, and enterprise technology companies.

Looking at IV’s 2025 patent acquisition data gives us quite a clear picture of who might be on their radar next:

Across recent enforcement campaigns, it has become increasingly clear that tracking both acquisition activity and litigation behavior of licensing entities is critical for managing exposure.

Using the acquisition data of just the past few months can give you a quick idea of whether your company or products could end up in litigation campaigns. 

In case this data seems useful for you, feel free to request access to our NPE litigation dashboard from here:

When enforcement activity is examined across these entities, clear technology clusters emerge. The technology themes associated with enforcement by these entities cluster predictably:

• multiplexing and VoIP implementations; 
• packet handling and interprocess communication in networking architectures;
• telecommunications infrastructure, including base-station coordination and wireless protocols;
• authentication frameworks with system management functions.

These patterns align closely with the technical domains covered by the major acquisitions of 2025. Estelgia LLC, having acquired 81 patents from Netgear Inc, joins entities with documented enforcement history in networking technologies. 

The Netgear portfolio likely encompasses packet handling, routing protocols, and network management implementations, domains where Estelgia has previously demonstrated assertion activity.

Telecommunications and Semiconductor Sectors Under Elevated Litigation Risk

Telecommunications carriers, infrastructure vendors, and device manufacturers face the most immediate exposure from 2025 acquisitions. The combined Peninsula and Apogee portfolios comprise 904 patents, concentrated in cellular technologies, with Peninsula’s standards-essential characterisation providing broad exposure across 5G-implementing companies. 

The Dish Wireless litigation demonstrates Peninsula’s targeting of network operators, but the technical scope suggests potential for expanded campaigns addressing handset manufacturers, chipset suppliers, and Radio Access Network infrastructure providers.

Semiconductor and memory manufacturers face distinct yet equally substantial risks. The Lodestar acquisition by Micron, combined with Palisade’s demonstrated enforcement activity, signals a greater likelihood of asserting in memory technologies. 

The patents span DRAM interface implementations, NAND Flash management systems, and memory controller architectures, technologies fundamental to products from multiple manufacturers. The “proxy war” characterisation suggests potential for sustained campaigns rather than isolated enforcement actions.

Consumer electronics face exposure through multiple acquisitions: FEC IP’s 232 patents from Funai Electric, Neolayer LLC’s 101 patents from AUO Corporation, and Prosperina Ventures LLC’s 121 patents from Intensity Lighting Company LLC. 

While these entities have not yet demonstrated enforcement with newly acquired portfolios, the technical domains of imaging systems, display technologies, and LED implementations align with commercially deployed products across numerous manufacturers.rd

Conclusion

As we see, in 2025, nearly 48% of all patent litigation, approximately 2,400 cases, were initiated by patent licensing companies. With enforcement timelines expected to shorten throughout 2026, companies in telecom, semiconductors, and consumer electronics are facing a much higher risk of being targeted.

Simply knowing these risks exist isn’t enough. You need a plan ready before you find yourself in a lawsuit against these patent licensing companies.

In our experience, the strongest evidence to win a lawsuit is often “hidden in plain sight.” For example, we’ve secured critical wins for our clients by digging into 3GPP email archives, technical discussions that most people overlook, but which often contain the exact proof needed to invalidate a patent.

Proactive risk management means finding these “silver bullets” now, rather than under the pressure of a deadline.

Let’s look at your current exposure and identify the specific patent invalidation strategies that will protect your portfolio in 2026.
