The Automotive Docket

Automotive companies faced 46 patent suits between August 2025 and August 2026. The vehicle divides the docket. Body, glass and accessories draw competitors. The electric drivetrain and everything connected to a network draw entities that build nothing, and they draw them exclusively.

Period
Aug 2025 to Aug 2026

Non practicing entities brought 26 of the 45 classified suits, or 57.8%. Operating companies brought 19. The two populations do not compete for the same subject matter.

Twenty two asserted patents sit in electric propulsion, wireless networks and network transmission. Every one of them was asserted by a non practicing entity. Thirteen patents sit in vehicle windows and body closures, and every one of those was asserted by an operating company.

The acquisition gap between the two sides is 68.2 points. Non practicing assertions were bought 86.2% of the time, operating company assertions 18.0%. An automaker adding electrification and connectivity is taking on the assertion profile of telecommunications alongside its existing one.

What this cannot tell you. The dataset records filings, parties and asserted patents, not results, so settlement rates, IPR institution rates and dismissal figures all fall outside it. Nothing here describes what a matter costs to defend or how it ends.

01

Using this on a live matter

Three questions answerable from public records in the first hour after a complaint or demand letter arrives, and what each answer usually means in this industry.

Which system is accused?

Electric propulsion, wireless and network patents were asserted 100% by non practicing entities across 22 patents. Windows and body closures were asserted 100% by operating companies across 13. In this industry the accused subsystem identifies the adversary before the asserter's name is researched.

Was the patent assigned after issue?

Acquired patents account for 86.2% of non practicing assertions and 18.0% of operating company assertions. That 68 point spread means assignment history sorts an automotive matter reliably.

How many claims are in the patent?

Operating company assertions here average 11.9 total claims and 1.9 independent. Non practicing assertions average 22.4 and 3.5. A short claim set on a mechanical part points toward a competitor dispute over a specific component.

02

Who is doing the asserting

57.8%

of classified cases came from entities that hold patents without building products.

That places automotive between mechanical and industrial at 50.0% and retail at 63.2%. It sits well below telecommunications at 88.0% and well above medical devices at 26.8%.

Twenty distinct non practicing entities filed the 26 cases on that side, and the largest brought four. This is a dispersed docket rather than a campaign, on both halves.

NPE, 26 cases (56.5%)Operating company, 19 cases (41.3%)Individual, university, government or unknown, 1 case (2.2%)

The 57.8% headline excludes the single unclassified case, and counting all 46 filings brings the non practicing share to 56.5%.

03

What a defensive portfolio reaches

A portfolio held for deterrence works by giving the other side something to lose if it is sued back. The mechanism needs an opponent whose own products can infringe.

2of 38

automotive companies sued here appear anywhere in this data as an asserting party.

Automakers and suppliers hold large portfolios, and this window records almost none of them being used offensively. The 20 non practicing entities that filed here sell nothing, so a countersuit has no target across the majority of the docket.

Where deterrence does reach, it reaches a specific kind of opponent. Operating company assertions here rest on patents the asserter filed 82.0% of the time, from families with a median of five members. These are narrow component patents rather than portfolios assembled for licensing.

Deterrence bears on the 42.2% of classified matters that operating companies bring, and none of the electrification or connectivity exposure sits inside that share.

04

Who is getting sued

Four companies with market capitalization above $200 billion absorbed 5 of the 46 cases. 21 companies with no public listing absorbed 21 between them, one case each.

Listed defendants absorbed 25 of the 46 cases from 17 companies, an average of 1.5 each, against exactly one apiece for the 21 private defendants. Repeat exposure in this industry belongs to the listed manufacturers and tier one suppliers. The private half of the docket is aftermarket, accessory and specialty vehicle companies, each appearing once.

05

What they assert on

Most asserted patents carry a primary CPC subclass. The six largest account for 57% of everything brought against automotive defendants, and four of them carry assertions from one side only.

Volume rose from 4 cases in 2024 Q3 to 18 in 2026 Q2. Non practicing filings moved from 3 to 11 and operating company filings from 1 to 7, so both sides grew. Quarterly counts in this industry run small enough that a single campaign would reshape the chart, and 2025 Q4 shows how far the total can fall back in one quarter.

Recent assertions by operating companies

Nineteen operating company suits landed in the window and thirteen were classified as disputes between direct competitors. The four most recent are below, and one of them is the largest patent count in this industry.

Two of the four shown involve aftermarket or replacement parts rather than vehicle manufacture, and one runs from a parts distributor against a manufacturer. Competitive relationship labels come from model classification in the source data rather than from court findings.

Automotive sits above the cross industry norm on acquisition and age, and twelve points above it on continuation share. The blended figures hide the split that section 06 shows, because averaging a bought communications portfolio with an original component patent produces a middle that describes neither. The two populations are worth reading separately in this industry more than in any other.

Twenty distinct non practicing entities brought 26 cases, so the average asserter appears once. No entity on either side filed more than four times. An asserter watchlist would have predicted almost none of this docket, while the technology split in section 05 predicts most of it.

Method & limits

Source. A patent litigation dataset of 21,217 patent case records across 7,841 distinct cases filed between 14 December 2017 and 10 August 2026, joined to 8,758 litigation parties and 21,165 asserter and defendant relationships. Industry is assigned on the defendant and entity type on the asserting party. The window runs from 21 August 2025 to 21 August 2026, and the latest filing anywhere in the data is dated 10 August 2026. Case counts are distinct cases, and patent level figures are averages over distinct patent case records. Family size is the INPADOC simple family member count, and technology area is the primary CPC subclass.

Definitions. Companies sued counts defendant records as the source data holds them, so spelling variants and affiliates of one group count separately, while asserter counts merge spelling variants of one name. A defendant is privately held when no market capitalization is on record for that entity, which places subsidiaries of listed companies in the private band. Size bands break at $2 billion, $10 billion and $200 billion. A company sitting exactly on a break falls in the higher band. Quarterly ranges describe the eight complete quarters from 2024 Q3 to 2026 Q2. Competitor suits are operating company suits in which at least one asserted patent is classified as a dispute between direct competitors. Technology area is the CPC subclass in first position on each patent, and the technology chart counts records asserted by non practicing entities and operating companies.

Classification is model assigned. Entity type, industry and competitive relationship are derived classifications rather than court designations or registry facts. Misreads on entity type run in one direction, with assertion entities labeled as operating companies. The non practicing share stated here therefore sits at the low end of its plausible range.

Known gaps. The dataset carries no outcome data of any kind, and venue is absent on most records in this period, so neither can be reported here. Continuation depth is unavailable, leaving only whether a patent is a continuation at all. Asserter names carry casing duplicates, which makes the per asserter counts lower bounds. 2026 Q3 covers filings through 10 August only and appears at reduced opacity throughout. With 46 cases in the window, single filings move the percentages materially, and the technology splits below rest on 96 classified patents.
