Coiled Tubing Patents: Who Leads, Where the Gaps Are 2026
Coiled Tubing Strings and Equipment Patents
Concentrated at the top. Five assignees hold 40.1% of all 932 records in scope, and ten hold 56.8% — a small group controls the core claim space around injectors, guide arches and bending-fatigue methods. Filings rose to a peak of 54 in 2018, then declined; the 2021-to-2024 window alone shows a drop from 46 to 15 filings, a 67% fall. Because publication typically lags filing by around 18 months, the 2025 and 2026 counts (down to 1 in 2026) are still incomplete and should not be read as a continued decline.

Common questions about coiled tubing patents
How many patents exist for coiled tubing strings and equipment?
This landscape identifies 932 published patent records filed or published between 2015 and mid-2026 that combine coiled tubing hardware terms with specific technical failure or performance modes such as bending fatigue life, ovality growth and internal corrosion. The true worldwide total for coiled tubing generally is larger, since this set is scoped to records that engage with those mechanistic terms rather than every coiled-tubing filing. Patent families, not raw document counts, are the fairer unit for comparing filing activity across jurisdictions.
Who are the leading patent holders in coiled tubing technology?
The ranking covers 100 companies, and it is concentrated: the top five hold 40.1% of all 932 records and the top ten hold 56.8%. One assignee leads clearly with 173 records, well ahead of the fifth-ranked company at 41 and the tenth at 25. This structure — a dominant leader plus a long tail of smaller filers — is typical of oilfield-services equipment categories with high capital costs of R&D.
Is coiled tubing patent filing activity increasing or decreasing?
Filing activity peaked in 2018 at 54 records and has generally declined since, with the 2021-to-2024 window showing a drop from 46 to 15 filings, a 67% fall. However, because patent publication typically lags actual filing by around 18 months, the very recent years in any dataset understate true activity, so the apparent drop to 2025-2026 counts should not be read as the field going quiet. 2024 is the most recent year that can be treated as reasonably complete.
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 Coiled Tubing Strings and Equipment 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.
