Landscape overview
An early-stage claim space built on general software architecture
This landscape covers 22 published records matching claims that combine API or web-API terminology with schema, request or parameter validation and a security, attack or abuse element. Filing activity is recent and thin relative to mature security fields: the trend runs from zero in 2017 to a peak of 12 filings in 2025, with the 2026 count still partial. Most records classify under general data-processing architecture rather than a dedicated security-hardware or protocol class, which suggests validation logic is typically claimed as part of a broader software system rather than as a standalone security feature.
Filing concentration is moderate rather than extreme: the top five assignees account for half of all records in scope, and the top ten reach just under three-quarters, leaving a real long tail of single-filing entrants. The most-cited record in the corpus traces back to a 2013-era web-services automation patent rather than anything filed in the current wave, a reminder that citation weight in a searched corpus tends to sit with older, foundational filings rather than the newest activity.

Filing data
Filing trends and technology composition
Twenty-two published records make up this landscape, spanning 2015 through the partial 2026 year. The distribution across IPC subclasses and receiving offices shows where API security validation claims currently concentrate.
Filing activity, 2017-2026
Filings sit at zero in 2017 and climb to a peak of 12 in 2025, with 3 records so far in the partial 2026 year. Because publication typically lags filing by around 18 months, the 2025 and 2026 counts will rise as more records surface.
Technology composition by IPC subclass
G06F (electric digital data processing) covers 59.1% of the 22 records in scope, well ahead of H04L (digital information transmission) at 27.3% and the tied pair of G06N and G06Q at 22.7% each. Since a single record can carry several IPC classes, these shares add up to more than 100%.
Shares are the percentage of the 22 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Integration platform for autonomous vehicles
UBER TECHNOLOGIES, INC.
Systems and methods are directed to facilitating secure, bidirectional communications between autonomous vehicles associated with a plurality of entities and a provider infrastructure. In one example, a computer-implemented method for facilitating communications with a vehicle includes obtaining, by a computing system comprising one or more computing devices, a communication associated with an autonomous vehicle via an application programming interface platform, wherein the application programming interface platform comprises a plurality of vehicle services interfaces. The method further includes determining, by the computing system, an entity-type of the autonomous vehicle.Abstract text abridged from the published filing.

What the numbers actually mean for a filing decision
Four figures from this dataset carry direct implications for where to file and who to watch.
Concentration
50.0%
of 22 records held by top 5 assignees
Half the field sits with a handful of filers
The top five assignees combined account for 50.0% of the 22 records in scope, with the leader alone holding 4. That leaves a long tail of single or double-filing entrants covering the remaining share, which is typical of a field still finding its dominant claim structures rather than one already locked up.
Top 10 combined reach 72.7% of all records.
Influence vs. volume
214 citations
on US8615731B2
One lineage anchors the citation graph
US8615731B2 and its related US8631386B2, both on automating web-service development around business rules, are the most-cited records in this corpus by a wide margin. High citation counts inside a searched corpus tend to favour older records, so treat this as a marker of past influence on the field's vocabulary, not a signal that the claim space is still open there.
Second-most cited record: US20200033847A1 at 27 citations.
Technology mix
59.1%
of 22 records carry G06F
Validation is filed as software architecture, not a security module
Nearly six in ten records in this set carry the G06F (electric digital data processing) class, well ahead of the network-transmission class H04L at 27.3%. That pattern suggests most applicants are folding request and schema validation into broader data-processing system claims rather than filing it as a discrete security feature.
G06N and G06Q each appear in 22.7% of records.
Filing geography
1 of 22
records route through the EPO
Europe is barely represented in this scope
The United States (9) and India (8) account for most receiving-office activity, with WIPO PCT filings adding 4 more. Only 1 record in this set routes through the EPO, which is a thin base for anyone assessing European freedom-to-operate on API validation claims specifically.
Receiving offices: US 9, India 8, WIPO 4, EPO 1.

Where to take this analysis
The figures above describe the field as it stands in this 22-record scope. Turning that into a filing or freedom-to-operate decision means going deeper on specific claims and assignees.
Check freedom-to-operate against the citation leaders
The two most-cited records in this corpus both trace to one automating-web-services lineage. Any new API validation filing should be checked against that lineage's claim scope before assuming clear space.

Half of the 22 records sit outside the top five assignees, spread across single or double filings. Watching this tail matters more in an early-stage field than tracking the leader alone.

Frequently asked
Questions practitioners ask about this landscape
This dataset contains 22 published records matching API security validation claims (schema, request or parameter validation combined with security, attack or abuse language) across the 2015-2026 coverage window. That is a small, early-stage field rather than a mature one. The most recent year is a partial count because publication lags filing by roughly 18 months, so the true 2025-2026 filing volume is understated in any snapshot taken today.
The ranked list covers 24 companies, and it is the complete set the underlying data returns — not a top-50 or top-100 cut. The leader holds 4 of the 22 records, and the top five assignees combined account for 50.0% of all records in scope, so roughly half the field's documented activity sits with a handful of filers while the rest is a long tail of one or two-filing entrants. Uber Technologies is among the named assignees, with a filing tied to autonomous-vehicle API communication.
General data-processing architecture (IPC class G06F) dominates, appearing in 59.1% of the 22 records in scope, which indicates that most filers treat validation as embedded logic within broader software systems rather than as a dedicated security module. Digital transmission (H04L) at 27.3% and AI-model computing (G06N) and business-process data processing (G06Q), each at 22.7%, show meaningful but secondary weight. Because records can carry multiple IPC classes, these percentages overlap rather than sum to 100%.
By raw volume it looks open: 22 records is a small corpus compared with mature software-security fields, and filing only began accelerating toward the 2024-2025 period, peaking at 12 in 2025. But citation concentration tells a different story for one specific claim lineage — US8615731B2, on automating web-service development, carries 214 citations, suggesting that anyone building general API-validation-as-business-rule-automation systems should check against that lineage first before assuming the space is empty.
The IPC subclasses with the thinnest coverage in this dataset — G05D (control of non-electric variables), G07C (time/attendance and checking devices) and H04M (telephonic communication), each at 9.1% of the 22 records — sit adjacent to the core validation claims but are not densely claimed. Geographically, the EPO route has only 1 of 22 records versus 9 through the United States and 8 through India, which suggests Europe-focused filing strategies currently face comparatively little documented prior art in this specific search scope.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown.
