Digital Twins in Manufacturing 

Digital Twins are virtual replicas of physical assets, processes, or systems that mirror their real-world counterparts in real time. In manufacturing, they are used to optimize production, predict failures, and simulate design changes. The integration of IP law into digital twins is complex because it involves multiple overlapping rights:

Patents – Protect inventions embedded in machinery or processes modeled in the digital twin.

Copyrights – Cover software, code, and possibly the 3D design models.

Trade Secrets – Protect proprietary process data, performance metrics, or analytics embedded in the digital twin.

Data Rights/Database Rights – In some jurisdictions, the data collected in digital twins may receive sui generis protection.

IP enforcement becomes challenging because digital twins often operate across borders, involve multiple stakeholders, and replicate both patented and secret processes virtually without physically reproducing machinery.

Case Laws Highlighting IP Enforcement in Digital Twin Contexts

1. Siemens AG v. Wabtec Corp. (U.S. Federal Court, 2020)

Background:
Siemens claimed Wabtec misused digital twin models of locomotive components that were provided under licensing agreements. The twins contained highly confidential operational parameters.

Legal Issue:
Whether using digital twins to simulate and improve competing products constitutes trade secret misappropriation.

Judgment:

Court held that even virtual replication of proprietary designs using digital twins could constitute misappropriation if trade secrets were used without authorization.

Emphasized that the method of accessing information—even digitally—is critical in determining infringement.

Significance:

Set a precedent that digital twins are legally equivalent to physical prototypes for IP enforcement.

Reinforced the importance of contractual safeguards and restricted access for virtual replicas.

2. General Electric v. Concept Laser GmbH (Germany, 2019)

Background:
GE alleged that Concept Laser’s digital twin software for additive manufacturing infringed its patents related to turbine blade design.

Legal Issue:
Whether simulating a patented physical object in a digital environment constitutes patent infringement.

Judgment:

German courts ruled that purely virtual simulation does not automatically infringe patents, unless the twin is used to produce or commercialize the patented object.

The court distinguished between research/simulation purposes and commercial exploitation.

Significance:

Highlighted jurisdictional differences in patent enforcement for digital twins.

Encouraged manufacturers to carefully define licensing agreements for digital twin simulations.

3. Dassault Systèmes v. Autodesk (France, 2018)

Background:
Dassault claimed that Autodesk’s software allowed users to create digital twins of its proprietary CATIA designs without authorization.

Legal Issue:
Whether copying 3D design files into digital twins constitutes copyright infringement.

Judgment:

French courts confirmed that 3D CAD models are copyrightable, and unauthorized replication—even in a virtual environment—can infringe.

Courts emphasized that the expressive element of the design, not just functional specifications, is protected.

Significance:

Reinforced that digital twins are protected under copyright law.

Manufacturers must license software and design models explicitly for twin creation.

4. ABB v. Mitsubishi Electric (Sweden, 2021)

Background:
ABB alleged that Mitsubishi used digital twins to reverse engineer ABB’s industrial robotics processes.

Legal Issue:
Can the digital replication of a process, rather than a physical product, constitute patent or trade secret infringement?

Judgment:

Swedish courts held that if a digital twin reveals confidential process methods, it can qualify as trade secret misuse.

However, general simulation of publicly known processes is not infringement.

Significance:

Highlighted that trade secret enforcement is often stronger than patent enforcement in digital twin contexts.

Emphasized the need for access control and NDA agreements in collaborative manufacturing projects.

5. BMW v. Tesla (Germany, 2022)

Background:
BMW claimed Tesla created digital twins of BMW electric vehicle components to benchmark performance.

Legal Issue:
Whether benchmarking using digital twins infringes IP rights.

Judgment:

German courts ruled that benchmarking is allowed if the original design was lawfully obtained and no proprietary software or confidential data was misused.

Digital twins cannot circumvent trade secrets or patented technology.

Significance:

Clarified boundaries between legitimate competitive analysis and IP infringement in digital twin use.

Highlighted need for IP clauses in joint R&D agreements involving virtual replicas.

6. Siemens v. Rolls-Royce (UK, 2017)

Background:
The case involved gas turbine manufacturers using digital twins to optimize performance and predict failures. Siemens claimed Rolls-Royce misappropriated its twin-based predictive models.

Legal Issue:
Is using another company’s twin-based analytics infringing IP rights?

Judgment:

UK courts ruled that unauthorized use of digital twin models containing trade secrets can constitute infringement, even without physical copying.

Emphasized access control and licensing as key to enforcement.

Significance:

Reinforced the legal equivalence of digital twins to physical prototypes.

Showed how IP enforcement adapts to virtual manufacturing technologies.

Key Takeaways for IP Enforcement in Digital Twins

Trade Secrets Are Critical – Most enforcement actions involve confidential operational data rather than the physical device.

Patents Have Limits – Patents protect physical and functional inventions but may not extend to pure simulation unless commercialized.

Copyright Protection – 3D models, software, and design schematics in digital twins are copyrightable.

Jurisdiction Matters – Enforcement varies widely across countries (Germany vs. U.S. vs. UK).

Contracts & Licensing Are Essential – NDAs, software licenses, and R&D agreements are the first line of protection.

In conclusion, digital twins blur the line between virtual and physical IP, creating new challenges for enforcement in manufacturing. Courts globally are increasingly recognizing digital twins as a legal subject of IP rights, particularly for trade secrets and copyright-protected models, while patent enforcement remains nuanced and jurisdiction-dependent.
