Lattice Based Cryptography Patents: Leaders & Filing Trends 2026
Lattice-Based Cryptography Implementation Patents
Concentrated but not locked up. the top 5 assignees hold 32.2% of the 500 records in scope and the top 10 hold 48.8%, leaving more than half the field to a long tail of single- and few-filing entrants. Annual filings rose from 18 in 2017 to a peak of 77 in 2023. The 2021-to-2024 span shows +17% growth (53 to 62). 2025 and 2026 figures will revise upward as publication catches up with filing — roughly an 18-month lag is typical — so treat the newest two years as a floor, not a signal of slowdown.

Common questions on this landscape
Who holds the most patents in lattice-based cryptography implementation?
One assignee leads the ranked field with 42 records, well ahead of the fifth-place holder at 26 and the tenth-place holder at 14. The drop-off is gradual rather than a sharp cliff, which means the leadership position is real but contestable rather than a locked-up monopoly. The ranking covers 100 companies total, and the top 10 combined account for 48.8% of the 500 records in scope, so more than half the field sits with companies outside that top group.
Is the lattice-based cryptography patent field still growing?
Yes, based on the years that have fully cleared publication: filings grew from 53 in 2021 to 62 in 2024, a +17% increase, with 2023 the peak year so far at 77. The 2025 and 2026 figures in the dataset will understate true filing activity because publication typically lags filing by around 18 months, so those years should not be read as a slowdown.
What technology areas do these patents actually claim?
Most records sit inside broader digital-transmission or general data-processing claims rather than standalone cryptography art: H04L (digital information transmission) covers 68.2% of the 500 records and G06F (electric digital data processing) covers 49.8%. The subclass specific to ciphering and secret communication, G09C, appears in only 6.6% of records, indicating that lattice arithmetic and hardware accelerator innovations are usually claimed as features embedded in a larger communication or computing system.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
Method: Filing trend and technology composition. Derived from a Patsnap search on Lattice Based Cryptography Implementation covering 2015–2026, data cut-off 2026-07-31. Counts reflect published records only and shift as new filings publish. Every share divides by all records in scope. Data: Patsnap Eureka. See the full landscape report.
