Application Trend 2014–2024
Patent families by earliest filing year and business entity breakdown.
A spike to 130 families in 2021 (from ~70 avg) signals a fundamental IP strategy change, driven by HQ doubling output, New Ventures emerging, and growing China operations. The 2023 peak of 161 families confirms a structural increase. 2024 data is incomplete (PATSTAT snapshot cutoff).
* 2024: Incomplete data due to ~18-month publication delay (PATSTAT Autumn 2025 Edition).

A61B 34/ (computer-aided surgery) exploded from 3 to 60 families — the single most dramatic technology shift. Combined with A61B 90/ (+920%) and endoscopy A61B 1/ (+1600%), B. Braun is building a comprehensive surgical robotics platform. Bioreactors (C12M 1/) are entirely new since 2021, and digital health (G16H) grew 300–400%. Meanwhile, traditional dialysis membrane tech (B01D 63/) is declining.
Grant Rate and Time-to-Grant
Grant performance by patent office for filings 2014–2022.
Data table: Grant Rates
| Office | Filed | Granted | Rate | Median Years |
|---|---|---|---|---|
| EP | 430 | 238 | 54.4% | 3.7 |
| US | 403 | 191 | 47.4% | 3.1 |
| JP | 57 | 39 | 68.4% | 4.5 |
| CN* | 281 | 197 | 70.1% | 0.8 / 3.5 |
| KR | 18 | 5 | 27.8% | 5.4 |
* CN: 185 utility models (0.8y median) + 12 invention patents (3.5y median). DE grant data not captured via publication kind codes.
Strong EP performance: 54.4% grant rate is above average for medtech. JP shows highest conversion (68.4%) due to likely pre-filing quality checks. CN utility models inflate the rate — but even invention patents grant faster (3.5y) than EP (3.7y). The US time-to-grant of 3.1 years is competitive.
Cooperation Partners
Joint applications (co-applicant analysis) revealing strategic R&D partnerships.
Data table: Collaboration Partners
| Partner | Focus | Joint Patents | Period |
|---|---|---|---|
| Universitat Politecnica de Catalunya | Photonics, surgical robotics | 16 | 2016–2022 |
| Fundacio Institut de Ciencies Fotoniques | ICFO, optical sensing | 3 | 2018–2022 |
| Nanjing Nuoyuan Medical Devices | Local manufacturing partner | 3 | 2024 |
| Koninklijke Philips N.V. | Health technology | 2 | 2018 |
| ICREA | Catalan research institution | 2 | 2018–2020 |
Barcelona cluster: B. Braun's strongest academic partnership is with UPC Barcelona and ICFO — 16+ joint families across 6 years, focused on surgical robotics and optical sensing. This aligns with B. Braun Surgical SA's presence in Barcelona and the explosive growth in A61B 34/ (surgical robotics) patents.
Limited collaboration breadth: Compared to peers, B. Braun files predominantly as sole applicant. Only 7 distinct cooperation partners were identified for 2014–2024. The Philips collaboration (2018) appears to be a one-off. Nanjing Nuoyuan (2024) suggests increasing Chinese local R&D integration.
Patent Family Size and International Scope
Average family size over time indicating international filing breadth.
Data table: Family Size by Year
| Year | Families | Applications | Avg. Size |
|---|---|---|---|
| 2014 | 84 | 230 | 2.7 |
| 2015 | 71 | 312 | 4.4 |
| 2016 | 64 | 264 | 4.1 |
| 2017 | 58 | 218 | 3.8 |
| 2018 | 70 | 218 | 3.1 |
| 2019 | 69 | 227 | 3.3 |
| 2020 | 74 | 237 | 3.2 |
| 2021 | 130 | 386 | 3.0 |
| 2022 | 85 | 215 | 2.5 |
| 2023 | 161 | 313 | 1.9 |
Average family size dropped from 4.4 (2015) to 1.9 (2023). This indicates more inventions filed initially at fewer offices — possibly more DE/EP first filings with national phase entries still pending. Combined with the PCT surge, this suggests a "file early, decide later" strategy. 2023/2024 families will likely grow as national phases are entered.
Future Technologies
Emerging technology areas identified through IPC-based analysis and title keywords.
Data table: Technology Emergence
| Technology | Families | First Year | Trajectory |
|---|---|---|---|
| Surgical Robotics (A61B 34/) | 63 | 2018 | Exponential |
| Digital Health (G16H) | 61 | 2014 | Strong growth |
| Connected/Smart/Digital (title) | 38 | — | Growing |
| Bioreactors (C12M) | 24 | 2021 | NEW since 2021 |
| Robotics (title keyword) | 16 | — | Growing |
| IoT / Sensors (title) | 13 | — | Growing |
| AI / ML (G06N) | 8 | 2016 | Emerging |
| Batteries (H01M) | 4 | 2016 | Minimal |
Three growth pillars: B. Braun's future technology strategy centers on (1) Surgical Robotics — the dominant growth area with 63 families since 2018, (2) Digital Health / connected devices — steady build across G16H and software interfaces, and (3) Bioreactors — a completely new technology domain since 2021, likely linked to cell therapy / biopharma manufacturing. AI/ML adoption is still nascent (8 families) but accelerating. Green tech, hydrogen, and batteries play no significant role.

Scope Limitations
- 2024 data is incomplete due to the ~18-month publication delay (PATSTAT Autumn 2025 Edition).
- Grant rates for applications from 2022 onwards are not meaningful due to ongoing examination.
- Time dimension uses earliest_filing_year from tls201_appln (priority year of the DOCDB family).
- NUTS regions from tls206_person.nuts field; labels from tls904_nuts reference table.
- PATSTAT's
han_nameharmonization may merge or split entities incorrectly in edge cases.
