High-Bandwidth Memory Patent Landscape 2026
High-Bandwidth Memory Patent Landscape in 2026
The High-Bandwidth Memory patent field is in a growth phase, with TSMC holding a commanding lead that is still expanding at +42% in recent filings. Activity is heavily concentrated among a small number of semiconductor and memory specialists, with the United States as the dominant filing jurisdiction.
TSMC leads a highly concentrated field with a commanding margin over all rivals
TSMC ranks first with 3,957 patent families, more than three times the count of the second-ranked applicant, Samsung Electronics, and the third-ranked Intel. This gap signals structural dominance rather than a competitive race at the top.
The top five filers — TSMC, Samsung Electronics, Intel, Semiconductor Energy Laboratory, and Micron Technology — together account for 59% of the combined total across the hundred largest filers, confirming a highly concentrated competitive structure with a steep drop-off beyond the top tier.

TSMC’s position, reinforced by a +42% recent-period momentum trend, suggests it is actively widening its lead. Intel (+19%) and Samsung (+24%) are also growing, indicating a three-way race for the top tier, while mid-tier players such as Semiconductor Energy Laboratory (-34%) and Micron (-43%) show declining recent activity.
Figures for 2024 and 2025 are subject to publication lag and will increase as pending applications publish; conclusions about the most recent periods should be treated as provisional. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Sustained filing growth with semiconductor device patents dominating the technology mix
Annual filing volume and IPC class distribution together reveal both the pace of competitive investment and the technical priorities shaping the High-Bandwidth Memory landscape.
Annual filing trend
Filings grew consistently from 592 in 2017 through a peak of 1,739 in 2023, reflecting a multi-year expansion phase. The 2024 figure of 1,642 represents a modest easing from the 2023 peak, and the 2025 and 2026 counts are substantially under-reported due to publication lag and should not be interpreted as a real decline.

H01L (Semiconductor devices) dominates the technology mix by a wide margin, followed at a distance by H10B (Memory device manufacture) and H10W. The concentration in H01L reflects that HBM innovation is primarily driven by packaging, interconnect, and semiconductor process engineering. Smaller but notable activity appears in G11C (Static and digital memories), G03F (Photolithography), and H02H (Protective circuit arrangements), pointing to adjacent specializations in memory circuit design, lithography materials, and ESD protection.

What the competitive structure means for R&D investment decisions
Four structural dimensions — maturity, concentration, collaboration, and geography — each carry distinct implications for teams deciding where and how to invest in HBM-related innovation.
Growth phase with filing volume still expanding on a multi-year basis
The field is classified as Growth stage: annual filings rose from 592 in 2017 to a peak of 1,739 in 2023, and while volume eased slightly in 2024, the multi-year trajectory remains upward. The 18% recent-window growth figure confirms continued expansion. Entry windows still exist, particularly in sub-classes where dominant players have lighter coverage.
Growth stageA three-player top tier dominates; mid-tier momentum is mixed
TSMC, Samsung, and Intel form a distinct top tier, each growing in recent periods (+42%, +24%, +19% respectively). The next tier — Semiconductor Energy Laboratory, Micron, Texas Instruments, and IBM — shows declining momentum (-34% to -83%), suggesting either strategic exits or portfolio consolidation. New entrants face high barriers from an entrenched IP estate concentrated in process and packaging.
Highly concentratedTSMC and Rohm & Haas / DuPont materials chains dominate co-filing activity
The most active co-filing pairs reflect intra-corporate coordination: TSMC with TSMC China (17 joint filings) and TSMC with TSMC Nanjing (9 filings), Texas Instruments with its Japanese affiliate (17 filings), and Rohm and Haas Electronic Materials with its Korean affiliate (15 filings) and with Dow Global Technologies (10 filings). Academic collaboration is present but modest: TSMC co-filed with National Yang Ming Chiao Tung University (6 filings) and National Taiwan University (6 filings). IBM’s collaboration with IBM United Kingdom (5 filings) rounds out the visible ecosystem.
Intra-group dominantUS leads filings decisively; China and Taiwan are the next most active jurisdictions
The United States is the primary filing jurisdiction, followed by China and Taiwan. Japan and WIPO PCT filings are the next tier. Europe via EPO and Germany together represent a meaningful secondary cluster, while South Korea — home to Samsung and SK Hynix — shows relatively modest direct filings, likely reflecting consolidated family strategies. India and Southeast Asia remain early-stage.

TSMC extends its lead while Intel and Samsung close the gap in the second tier
The top players are differentiated not only by portfolio size but by recent trajectory and technology focus within semiconductor device classes.
Taiwan Semiconductor Manufacturing Co.
TSMC holds 3,957 patent families — more than three times the count of the next-ranked applicant — with its focus concentrated across H01L 21 (semiconductor fabrication), H01L 23 (semiconductor packaging), and H01L 25 (multi-chip assemblies). Its recent-period momentum of +42% indicates the portfolio is actively expanding, reinforcing a lead that appears structural rather than historical.
families: 3,957Samsung Electronics Co., Ltd.
Samsung ranks second with 1,253 patent families, showing +24% recent-period growth. Its technology emphasis parallels TSMC’s — H01L 21 and H01L 23 dominate — but Samsung also has notable coverage in H01L 25 (stacked/multi-die), reflecting its integrated memory-plus-logic stack strategy. Intel, with 1,192 patent families and +19% momentum, sits nearly level with Samsung and similarly focuses on H01L 21, H01L 23, and H01L 27 (integrated circuits).

Under-served adjacent branches worth monitoring for targeted entry
Several IPC classes sit adjacent to the dominant H01L core with comparatively sparse coverage. These are observations of relative sparsity; their value as entry points depends on technical fit and organizational capability.
H02H · Protective Circuit Arrangements
With 733 patent records at a 3% share, ESD and over-voltage protection circuitry for HBM interfaces is an adjacent branch that remains relatively sparse relative to the overall corpus. As HBM stacks operate at finer process nodes and higher I/O densities, robust on-die and interposer-level protection circuits become critical reliability requirements. Qualcomm’s existing H02H 9 coverage (50 records) and the broader HBM ecosystem’s focus on H01L suggest that focused IP development in protection circuit topologies tailored to HBM signaling environments represents a plausible, technically motivated entry path for circuit IP specialists.
Search this in Eureka →G11C · Static & Digital Memories
G11C covers memory cell circuits, sense amplifiers, and read/write control logic, and appears at 715 patent records and a 3% share — notably sparse given that HBM is fundamentally a memory technology. The dominant activity in H01L (physical semiconductor devices) and H10B (memory manufacture) suggests most filers have prioritized physical implementation over circuit-level architecture. Teams with expertise in memory array timing, refresh control, or error correction at the circuit architecture level may find less-crowded ground here, with relevance to next-generation HBM standards requiring lower latency and higher reliability.
