Drilling Jars and Shock Tools Patents: Top Companies & Trends 2026
Drilling Jars and Shock Tools Patents: Who Leads and Where Filing Concentrates
38.7% sits with five companies. The top five assignees combined account for 133 of the 344 records in scope, with a long tail of single- and few-filing entrants behind them. Activity climbed to a peak of 29 records in 2020, then settled into a lower but rising pattern; 2021 to 2024 alone shows filings roughly tripling, a +200% increase from 2 to 6. The final one or two years in the chart will fill in further as publications catch up with filing dates.

Common questions about drilling jar and shock tool patents
Who holds the most patents on drilling jars and shock tools?
One assignee leads the ranked list with 31 records, ahead of the fifth-ranked company at 23 and the tenth-ranked company at 10. The top five assignees combined hold 133 of the 344 records in scope, or 38.7%, and the top ten extend that to 54.7%. Below that point the ranking, which covers 93 assignees total, thins into a long tail of companies with only a handful of filings each, so no single company controls the field outright.
Is patent filing for drilling jars and shock tools growing or slowing down?
Filing activity peaked in 2020 at 29 records, and the years since have moved at a lower but rising pace: from 2021 to 2024, the last year that can be treated as reasonably complete, recorded filings grew from 2 to 6, a +200% increase. The most recent one to two years in any chart will look artificially low because patent publication typically lags the filing date by around 18 months, so those figures should not be read as a real decline.
What technology areas do drilling jar patents actually cover?
The core of the field, at 92.7% of the 344 records, falls under E21B, the IPC subclass for earth and rock drilling equipment. Smaller but consistent activity appears in G01V geophysics and survey instruments (4.9%) and F16F springs and vibration dampers (4.1%), reflecting the shock-absorption and downhole-sensing functions that pair with the core mechanical jar design. Valve mechanisms, measurement instruments, and a couple of mechanical-transmission classes each account for 1.5% or less.
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 Drilling Jars and Shock Tools covering 2015–2026, data cut-off 2026-07-31.
