Not every innovation is patent-worthy. Understanding the criteria can save time and resources.


Your invention must be new.

  • Prior Art Search: Before filing, conduct a thorough search to ensure no similar invention has been published or patented.
  • Beware of Self-Infringement: Disclosing your invention in a publication or conference before filing can jeopardize its novelty.


It shouldn’t be an obvious iteration to someone skilled in the field.

  • Incremental vs. Revolutionary: While revolutionary inventions are clear-cut, even incremental advancements can be patented if they offer significant benefits or solve longstanding problems.
  • Expert Testimony: In borderline cases, an expert’s perspective on the non-obviousness of your innovation can bolster your patent application.


The invention must have a practical and beneficial use.

  • Clinical Relevance: Especially in medical devices, the utility is often tied to clinical outcomes. Demonstrating the device’s impact on patient care can strengthen the utility argument.
  • Functional Prototypes: Having a working prototype, possibly through a 3D-printed version, can serve as tangible proof of utility.

Navigating Regulatory and Ethical Concerns

Medical devices, given their direct impact on human health, come with added layers of complexity.

FDA and Regulatory Approvals

  • Clinical Trials: Some devices may require clinical trials. While a patent protects your idea, regulatory bodies ensure its safety. Collaborate closely with regulatory experts to ensure compliance.
  • Expedited Pathways: For breakthrough devices, the FDA and other bodies might offer accelerated approval pathways. Understand these to fast-track your device’s market entry.

Ethical Considerations

  • Patient Safety: Always prioritize patient safety. Ethical lapses can not only jeopardize patent applications but also tarnish brand reputation.
  • Data Privacy: If your device collects patient data, ensure robust mechanisms to protect this data, complying with regulations like GDPR or HIPAA.

Crafting a Robust Patent Strategy

Armed with insights, it’s time to weave a patent strategy.

Global vs. Regional Patents

  • PCT Applications: The Patent Cooperation Treaty (PCT) allows you to file a single patent application that can be valid in over 150 countries. It’s a cost-effective way to secure international protection.
  • Key Markets: If global protection isn’t viable, prioritize markets with the most significant revenue potential or where infringement risks are high.

Continuation and Provisional Applications

  • Continuous Innovation: As you refine your device, file continuation applications to expand the scope or detail of your original patent.

Collaborations and Licensing

  • Joint Ventures: Collaborating with other companies can combine strengths, leading to stronger patents and shared protection responsibilities.
  • Licensing Out: If direct commercialization isn’t viable or isn’t your forte, licensing your patented methods to established medical device manufacturers can be lucrative.

Defensive and Offensive Patent Tactics

In the competitive arena of 3D-printed medical devices, having a multi-pronged patent approach can be invaluable.

Building a Patent Thicket

Creating a dense web of patents around your core invention can deter competitors.

  • Core vs. Peripheral Patents: While your main innovation is central, securing patents on auxiliary processes, materials, or technologies can make infringement by competitors more difficult.
  • Cross-Licensing Opportunities: With a robust patent thicket, you might find other companies interested in cross-licensing deals, allowing both parties to utilize each other’s patented technologies.

Monitoring and Enforcement

Staying vigilant about potential infringements is pivotal.

  • Regular Patent Watches: Subscribing to services that alert you about newly filed patents in your domain can help in early detection of possible infringements.
  • Legal Recourse: Having a legal team or expert on retainer who specializes in patent law can expedite processes if enforcement becomes necessary.

Freedom to Operate (FTO) Analysis

Before commercializing, ensure you’re not infringing on others’ rights.

  • Comprehensive Searches: Beyond just patents, this involves scouring databases, publications, and even product catalogs to ensure your device doesn’t infringe on existing rights.
  • Mitigation Strategies: If potential infringement risks arise, strategies like redesigning the product, acquiring licenses, or even purchasing the concerning patents can be explored.

Dealing with Patent Trolls

In the patent world, entities called “patent trolls” or “non-practicing entities (NPEs)” exist. They accumulate patents not to commercialize, but to extract licensing fees or sue alleged infringers.

Recognizing Patent Troll Behavior

Identifying such entities early on can save headaches.

  • Lack of Commercialization: If an entity holds many patents in the 3D medical printing realm but doesn’t seem to have any products, they might be an NPE.
  • Litigation History: Often, patent trolls have a history of frequent litigations against innovators. A quick legal background check can be revealing.

Best Practices Against Trolls

  • Strong Patent Documentation: Ensuring your patents are well-drafted, with clear claims and comprehensive specifications, can deter trolls who look for easy targets.
  • Join Defense Aggregates: Collaborative entities that pool resources to buy potentially threatening patents before trolls can, or even collectively defend against them, can be beneficial.

Intellectual Property Beyond Patents

While patents are pivotal, other IP assets can complement your protection strategy.

Trade Secrets

Some processes or innovations might be better kept secret.

  • When to Opt for Secrets: If an innovation is hard to reverse engineer and can be kept secret within your organization, trade secrets might be more strategic than patents.
  • Non-disclosure Agreements (NDAs): Ensure employees and collaborators sign NDAs to legally bind them from disclosing or using your secrets.

Copyrights and Trademarks

While not central to device protection, they can bolster your IP arsenal.

  • Software Components: If your 3D-printed device integrates software, copyrights can protect that software element.
  • Branding: Trademarks safeguard your device’s brand name, logo, or even specific design elements, building brand equity and deterring copycats.

Leveraging Patents for Funding and Valuation

For startups, patents can significantly impact valuation and investment attractiveness.

Patents as Assets

  • Asset Value: A robust patent portfolio can be reflected as a tangible asset in your books, enhancing company valuation.

3D printing often relies heavily on software, both for design and execution.

  • Integrated Patenting: If your device’s uniqueness stems from a blend of hardware and software, ensure your patent application seamlessly integrates both aspects.
  • Open Source Considerations: Using open-source software can be cost-effective but be wary of licensing terms. Some open-source licenses can jeopardize the exclusivity of your innovations.

Post-Patent Considerations

Once your patent is granted, the journey isn’t over. Here’s how to extract maximum value from your patent and ensure it remains enforceable.

Monetizing Your Patent

A granted patent can be a revenue stream, not just a shield.

  • Licensing: If commercializing the device isn’t viable for you, licensing your patent to bigger players can be lucrative.
  • Patent Sales: In some cases, outright selling the patent might be more strategic, especially if it’s peripheral to your core business.

Maintenance and Renewals

Patents aren’t a one-and-done deal. They require periodic maintenance.

  • Pay Renewal Fees: Most jurisdictions require annual fees to keep the patent active. Budget for these and ensure timely payments.
  • Monitor Market Changes: If the market shifts and your patented device no longer holds commercial value, it might be economical to let the patent lapse rather than pay renewal fees.

Defensive Publications

In some scenarios, preventing others from patenting might be more strategic than patenting yourself.

  • Why Opt for Defensive Publishing: If you have an innovation that complements your patented device but isn’t worth patenting itself, publishing it ensures others can’t patent it either.
  • Cost-effective Defense: Defensive publishing is considerably cheaper than patenting, serving as a budget-friendly defensive tactic.

Building an Internal IP Culture

For startups, ensuring every team member is aligned with your IP goals can be pivotal.

Regular IP Training

  • Onboarding Sessions: Every new team member, irrespective of their role, should understand the basics of IP and its significance to your startup.
