Sensor Diagnostics and Self-Validation Patents
96.8% concentration. The top five assignees hold 358 of the 370 records in scope, leaving a long tail of single-digit filers with little room at the top. Filings ran from 37 in 2017 to a peak of 51 in 2018, then eased across the following years; 2021 to 2024, the last year treatable as complete, fell from 16 to 9, a 44% decline over that span. 2025 and 2026 figures are still filling in given the roughly 18-month publication lag and should not be read as a continued drop.

Common questions on this landscape
Who holds the most patents in sensor diagnostics and self-validation?
The ranked field of 44 companies is heavily concentrated at the top: the leading assignee alone accounts for 314 of the 370 records in scope, and the top five combined hold 96.8% of all records. That leaves a long tail of single- or double-digit filers, so due diligence should focus most attention on the leader's portfolio rather than spreading evenly across the ranking.
Is patent filing in this field growing or slowing down?
Filings peaked in 2018 at 51 and eased afterwards; the most recent complete comparison, 2021 to 2024, shows a drop from 16 to 9 filings, a 44% decline. Figures for 2025 and 2026 are still incomplete because publication typically lags filing by about 18 months, so it is not yet possible to say whether the field is still contracting or simply under-reported for those years.
What does US10353018B2 actually cover?
US10353018B2, granted to Infineon Technologies AG in 2019, covers integrated-circuit sensor diagnostics that use multiple communication signal paths where at least one path is diverse from the others in hardware, software, processing or operating principle. It is not limited to a single sensor type; the abstract explicitly extends to a variety of sensor implementations and applications. Anyone designing on-chip redundant diagnostics should check whether their path diversity clears this claim before assuming simple duplication is safe.
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 Sensor Diagnostics and Self-Validation 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.
