Package Level Nondestructive Analysis Patents: Mapping Who Files and Where the Field Is Still Open
50.9% concentration at the top. The five leading assignees hold 163 of the 320 records in scope, but filings past that group thin out into a long tail of single- and double-digit filers. Filings peaked at 18 in 2017 and have since settled into a lower, flatter band; 2021 and 2024 both post 6 filings, a 0% change across that span. The final one or two years in the series are undercounted because publication trails filing by roughly 18 months.

Common questions about this landscape
What counts as package level nondestructive analysis in a patent search?
It covers inspection techniques applied to a sealed integrated circuit or component package without opening or destroying it, chiefly scanning acoustic microscopy, X-ray tomography and acoustic micro imaging. In this dataset the search pairs those modalities with specific defect or interpretation problems: delamination detection, voids in solder, wire sweep, resolution limits, sample orientation and artifact interpretation. That combination is what separates this landscape from general X-ray or acoustic imaging patents that are not tied to package-level defect analysis.
Who are the leading patent holders in this space?
The ranking covers 92 assignees drawn from the 320 records in scope, with the single leading assignee holding 89 records and the top five combined holding 163 records, or 50.9% of the total. Several of the top holders are related entities that co-file together, which concentrates the leading position within one corporate cluster rather than spreading it across independent competitors. Beyond the top ten, which together hold 66.9% of records, the remaining assignees each hold a small number of filings.
Is filing activity in this area growing or shrinking?
Filing counts peaked at 18 in 2017 and have since settled lower, with complete-year data showing 6 filings in both 2021 and 2024 — a 0% change across that span. That reads as flat rather than declining. The most recent one to two years in any such trend are always understated because publication typically lags actual filing by roughly 18 months, so it is too early to call the 2025-2026 dip a real slowdown.
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 Package Level Nondestructive Analysis 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.
