Modular Engine Architecture Patent Snapshot 2026
The corpus is extremely concentrated, with Pratt & Whitney Canada Corp accounting for the dominant share of ranked patent records and gas-turbine plant technology (F02C) forming the core of all activity. Filing volume is minimal and heavily skewed toward a single applicant, signaling an early-stage or narrowly scoped niche rather than a broad competitive race.
Pratt & Whitney Canada leads an extremely concentrated field
Pratt & Whitney Canada Corp holds the top position in the applicant ranking with 8 patent records, followed at a distance by Hindustan Aeronautics Limited with 1 patent record — together they account for all ranked filers in the corpus.
The top five filers’ share of the ranked applicants visible in this query stands at 100%, underscoring a field with virtually no distributed competition: two organizations account for the entirety of ranked activity, with no meaningful second tier.
| # | Applicant | Patent records | Share |
|---|---|---|---|
| 1 | PRATT & WHITNEY CANADA CORP | 8 | |
| 2 | Hindustan Aeronautics Limited | 1 |
This extreme concentration implies that Pratt & Whitney Canada effectively defines the current intellectual-property frontier for modular engine architecture as scoped here; any entrant would be navigating a evidence snapshot where a single incumbent holds most of the established positions.
The most recent filing periods should be treated cautiously given typical patent publication lags of 18–24 months; apparent inactivity in 2024–2026 does not reliably indicate a halt in R&D. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Activity is sparse and gas-turbine technology dominates the technology mix
The annual filing trend and IPC composition together reveal a narrow, specialist corpus anchored in gas-turbine engineering, with isolated filing events rather than sustained annual volume.
Annual filing trend
Filing activity is effectively flat across the observed window, with a single record logged in 2023 and zero in surrounding years. This pattern reflects either a very narrow search scope or genuinely limited dedicated patenting; the most recent years (2024–2026) are subject to publication lag and should not be read as confirmed zero-activity periods.

F02C (Gas-turbine plants) accounts for the largest share of IPC-coded records, followed by F01D (Turbines and non-positive displacement engines), F02K (Jet and reaction propulsion), and F28D (Heat-exchange apparatus). This mix is consistent with turbofan bypass and thermal management sub-systems being the primary technical focus within modular engine architecture as scoped.

Turbofan bypass duct air cooled fluid cooler insta…
A cooling apparatus for cooling a fluid in a bypass gas turbine engine comprises a heat exchanger disposed within a bypass duct and accommodated by a sub-passage defined by a flow divider affixed to an annular wall of the bypass duct. The sub-passage defines an open upstream end and an open downstream end to direct a portion of the bypass air flow to pass… (excerpt from the patent abstract)

Ranked by total forward citations. Citation counts favour older and broadly cited patent families, and broad or adjacent patents may appear when they match the search scope. Treat this section as citation context, not as a curated list of the most topic-specific patents. Some patent titles may be shown in their original, non-English language where an accurate translation could not be guaranteed.
Assignee snapshot from the current evidence set
The applicants below are visible in this query result. Because the evidence set is relatively small, read this section as a directional snapshot rather than a full competitive ranking.
Pratt & Whitney Canada Corp
Pratt & Whitney Canada Corp holds 8 patent records, all concentrated in gas-turbine plant sub-classes F02C7, F02C9, and F01D25, with additional coverage in heat-exchange apparatus (F28D). The corpus does not include a momentum trend figure for this applicant, but their established multi-record position and broad IPC spread indicate a mature internal program rather than a recent entry. Their turbofan bypass and thermal management filings define the technical baseline for this landscape.
patent records: 8Hindustan Aeronautics Limited
Hindustan Aeronautics Limited holds 1 patent record and is flagged as a new entrant in applicant momentum data. Their technology focus spans F02C6, F02C7, and F02C9 — overlapping with Pratt & Whitney Canada’s core gas-turbine classes — which positions them as a direct, if nascent, participant rather than a complementary niche filer. Given the new-entrant signal and India jurisdiction coverage, their trajectory warrants monitoring for follow-on filings.
patent records: 1Frequently asked questions
There is 1 patent family in scope. The applicant ranking and IPC counts are reported at the patent-record level, which can exceed the family total because a single family may be filed across multiple jurisdictions or IPC classes.
Pratt & Whitney Canada Corp is the leading filer with 8 patent records, far ahead of the only other ranked applicant, Hindustan Aeronautics Limited, which holds 1 patent record.
F02C (Gas-turbine plants) is the visible IPC class with 7 patent records. F01D (Turbines and non-positive displacement engines), F02K (Jet and reaction propulsion), and F28D (Heat-exchange apparatus) each appear with 2 records.
Europe (EPO) leads with 3 patent records, followed by the United States with 2, and Canada, Germany, India, and WIPO (PCT) each with 1 record.
No. All collaboration pairs in the evidence link individual named inventors to Pratt & Whitney Canada Corp. There is no recorded cross-institutional or industry-academia co-filing in this corpus.
No. Patent applications typically take 18–24 months to publish after filing. The apparent absence of records in 2024–2026 reflects publication lag rather than confirmed inactivity, and those periods should not be used to infer that R&D or filing has stopped.

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. As a result, the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
