A global study of semiconductor patent filings by Anaqua reveals that patenting at the intersection of artificial intelligence and semiconductor hardware grew 114% over a five-year period, significantly outstripping the 78% growth seen across the broader semiconductor sector. The data shows distinct competitive strategies: Samsung leads in integrated circuit architecture and high-bandwidth memory (HBM), while Chinese state-affiliated institutions lead in volume across AI inference and custom accelerators. For corporate IP counsel, these shifts demand immediate portfolio benchmarking against domain-specific hardware classifications rather than broad semiconductor categories.
On September 1, 2026, intellectual property management provider Anaqua released findings from its 2026 Semiconductor Industry Patent Report: AI & Innovation Trends. The study evaluated 713,755 semiconductor filings over a five-year window, including more than 174,000 filings in the most recent 12-month period, extracted using its AcclaimIP analytics platform between May and June 2026.
According to the report, filings combining AI and semiconductor technologies grew nearly 40% faster than general semiconductor patenting. The findings highlight sharp divergences in corporate IP portfolios:
The acceleration of AI hardware filings reflects a transition from general-purpose computing toward specialized accelerators, domain-specific integrated circuits, and heterogeneous memory packaging. As training and inference workloads face memory bandwidth bottlenecks and thermal constraints, R&D investments have shifted toward architectural innovations such as PIM, analog weight encoding, and HBM stacking.
The data also reflects geopolitical dynamics. Following export controls on advanced computing hardware, Chinese domestic research institutions and regional startups have scaled high-volume domestic patent applications in inference and graphics processing. Conversely, established Western fabless leaders like NVIDIA rely heavily on proprietary software frameworks, resulting in narrower hardware patent footprints relative to integrated device manufacturers and traditional systems vendors.
The concentration of filings across architecture, inference, and HBM directly alters freedom-to-operate (FTO) risk profiles for fabless designers, memory vendors, and foundries.
For South Korean memory and logic manufacturers, Samsung's top rankings in AI architecture (1,194 filings) and HBM (107 filings) demonstrate an effective conversion of traditional DRAM fabrication leadership into enforceable positions across high-bandwidth interfaces and processing-in-memory. Korean filers operating in memory-adjacent spaces can rely on standard-essential and implementation claims covering physical chip interconnects, microarchitectural data paths, and low-power analog circuits.
However, the sheer volume of Chinese inference filings (5,387 across state entities) creates a dense defensive thicket for any company prosecuting or enforcing hardware claims in East Asia. Outside patentees must recognize that Chinese institutions frequently act as prior art sources in examination and invalidation proceedings before CNIPA and KIPO. While Korean amendment practice under Article 47(2) of the Patent Act strictly limits amendments to the scope of features directly and unambiguously derivable from the original specification, examiners frequently cite foreign state-funded patent disclosures against architectural claims.
Actionable Prosecution and Portfolio Step: IP prosecution teams must audit pending semiconductor applications to ensure claims are not limited strictly to algorithmic descriptions. Patent attorneys should draft multi-layered independent claims that explicitly recite structural hardware limitations, such as register transfer logic, on-die interconnect topologies, memory bus line structures, and physical weight-storage memory cells (e.g., PIM or phase-change structures), to survive subject-matter eligibility scrutiny and provide clear literal infringement readouts against competing silicon.
As cloud service providers increasingly design custom ASICs like Google TPUs and Microsoft Maia chips, patent disputes will likely expand beyond traditional chipmakers to include hyperscaler server infrastructure and custom silicon supply chains. Practitioners should monitor upcoming grant distributions in hybrid analog-digital circuits and advanced packaging interfaces.
In the interim, corporate IP counsel should perform a targeted whitespace analysis across their inference and memory-interface portfolios. Companies designing edge AI or data-center accelerators should conduct FTO clearances against the rapidly growing published portfolios of Chinese state institutions and regional fabless startups, mapping active competitor claims against physical die layouts and packaging interconnect specifications before tape-out.
