Composite repair and bonded joint assessment patents: mapping who is filing and where the claim space is still open
A robotics-heavy leader. The top filer sits at 14 records against a field where fifth place holds just 1, with recent-year momentum flat across the ranked assignees. Filings climbed unevenly from a single record in 2017 to a peak of 10 in 2022, the highest year in the dataset. The 2026 figure reads as zero only because the year is partial and recent filings have not yet published.

Common questions on this landscape
How many patents cover composite repair and bonded joint assessment?
This dataset captures 32 published records matching composite repair and bonded joint assessment search terms, covering filings from 2015 through mid-2026. The count includes both aerospace-specific structural repair filings and adjacent applications such as wind turbine blade repair. Because publication typically lags filing by around 18 months, the true number of filed applications in the most recent one to two years is understated in this figure.
Who are the leading patent filers in composite repair technology?
The ranking returned by this dataset covers 9 companies and individuals, with the leading assignee holding 14 records against a fifth-place entrant with just 1. That is a steep drop-off rather than a gradual one, indicating a single organisation with a sustained filing programme surrounded by a long tail of occasional filers, including universities and individual inventors. Recent-year momentum for the leader reads flat, so the gap has not been widening in the latest available data.
What is kissing bond detection and why does it show up in these patents?
A kissing bond is a bonded joint defect where two surfaces are in contact but have little or no adhesive strength between them, making it very difficult to detect with standard visual or basic ultrasonic inspection. It shows up in this patent set because reliable detection of kissing bonds is one of the core technical problems bonded joint assessment patents try to solve, alongside adhesive bondline thickness control and surface preparation. It remains one of the sub-areas in this landscape without a single dominant filer, which points to open claim space for improved detection methods.
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 Composite Repair and Bonded Joint Assessment 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.
