Back to the Basics: What is a patent and what can it protect?

Back to the Basics: What is a patent and what can it protect?

Recently a new client came to me regarding whether his invention was patentable. I thought about this post and thought I’d repost it.

This is the first in a series of informational posts designed to demystify the core pillars of intellectual property law. Today, we focus on the patent: what it actually is and the specific protections it offers once granted by the government.

In the United States, there are three primary types of patents: UtilityDesign, and Plant. Each serves a different purpose and offers a different window of protection.

1. Design Patents

Design patents protect the new, original, and ornamental aspects of a functional item. They don’t cover how a product works, but rather how it looks.

  • Examples: The iconic shape of an iPhone® or the sleek curves of a Corvette® sports car.
  • Term: Under current law, design patents have a life of 15 years from the date the patent is granted (for applications filed on or after May 13, 2015).

2. Plant Patents

A plant patent is a specialized grant for anyone who has invented or discovered—and asexually reproduced—a distinct and new variety of plant.

  • Requirement: The variety must be “asexually reproduced,” meaning it is grown from something other than a seed (like a cutting or grafting).
  • Term: Protection extends 20 years from the date of filing.

3. Utility Patents

Utility patents are the most common type and protect the “utility” or function of an invention. These cover:

  • Articles of manufacture (physical products)
  • Methods of manufacture (industrial processes)
  • Compositions of matter (chemical formulas or pharmaceuticals)
  • Business methods (often seen in the software and fintech sectors)

A Note on Software & Business Methods: This last category—business methods—remains a highly active area of legal debate in 2026. While they are still patentable, recent court decisions like Constellation Designs v. LG have reinforced that these patents must describe a specific technological solution rather than just a general “abstract idea.”

Requirements and Maintenance

To qualify for a utility patent, an invention must meet three strict criteria: it must be usefulnovel (new), and non-obvious to someone skilled in that specific field.

A utility patent generally lasts for 20 years from the date of filing. However, the protection isn’t “set it and forget it.” To keep a utility patent active, you must pay maintenance fees to the US Patent and Trademark Office (USPTO) at three critical intervals:+1

  1. 3.5 years after issuance
  2. 7.5 years after issuance
  3. 11.5 years after issuance

Failure to pay these fees (which have seen significant updates as of 2025/2026) will result in the patent expiring early and your invention falling into the public domain.

Protecting your innovative developments is a critical component of any successful organization. Deciding when to file—and which type of patent best fits your business goals—is a decision that shouldn’t be made alone.

International Medical Devices: A Hard Lesson Learned

International Medical Devices: A Hard Lesson Learned

Recently, the U.S. Court of Appeals for the Federal Circuit issued a significant reversal of a California district court’s finding of trade secret misappropriation. In the case of International Medical Devices, Inc. (IMD) v. Cornell (April 2026), the court ruled that no reasonable jury could have found several alleged trade secrets to be, in fact, “secrets.”

The Dispute: Cosmetic Penile Implants

The litigation centered on the Penuma® cosmetic penile implant. The plaintiffs alleged that four specific elements of their technology were stolen trade secrets:

  1. Structural Pockets: Internal voids within the implant to enhance softness and elasticity.
  2. Mesh Tabs: Components around the distal tip to facilitate tissue ingrowth.
  3. Absorbable Sutures: Used in combination with mesh tabs to hold the implant during initial healing.
  4. The “Supply List”: A specific list of materials and instruments used to perform the surgical implantation.

The “Death” of a Trade Secret: Public Disclosure

The Federal Circuit held that the first three alleged secrets (the structural design elements) were ineligible for protection because they had already been disclosed in prior patents.

Citing the precedent in Atl. Rsch. Mktg. Sys., Inc. v. Troy, 659 F.3d 1345, the court reaffirmed a fundamental rule of intellectual property:

“A trade secret is secret, a patent is not. That which is disclosed in a patent cannot be a trade secret.”

Because these design concepts appeared in public patent filings—some dating back decades—they were part of the public domain. You cannot claim “secrecy” over information that the government has already published for the world to see.

The Failure of Internal Protection

The fourth alleged trade secret—the list of surgical instruments—failed for a different reason: lack of reasonable efforts to maintain secrecy.

The plaintiffs had emailed this list to the defendant without any:

  • Confidentiality caveats
  • “Trade Secret” labels
  • Explicit instructions on restricted handling

Under the California Uniform Trade Secrets Act (CUTSA), information only qualifies as a trade secret if the owner takes active, reasonable steps to keep it secret. Because the plaintiffs treated the list as ordinary correspondence in the past, they could not retroactively claim it was a protected secret during litigation.


The Takeaway: How to Protect Your Innovation

This case serves as a vital reminder for tech and medical device companies: If you have a trade secret, keep it that way.

  • Audit Your Patents: Ensure you aren’t trying to protect information as a “secret” if it’s already described in your (or someone else’s) patent filings.
  • Use NDAs Every Time: Never disclose sensitive information to an outside individual or organization without a signed Non-Disclosure Agreement (NDA).
  • Label Everything: Mark confidential documents clearly as “Trade Secret”, “Proprietary” or “Confidential.”
  • Need-to-Know Access: Limit employee access to sensitive data and provide regular training on internal security protocols.

U.S. Patent Office Waives Fee For AI Search Automated Pilot Program

U.S. Patent Office Waives Fee For AI Search Automated Pilot Program

A patentability search and assessment is always recommended when evaluating whether your invention would be entitled to meaningful patent protection. The search also helps to inform the inventor and patent attorney where there may be areas of more narrow protection and draft accordingly.

The United States Patent Office recently launched the AI Search Automated Pilot Program. The program is designed to evaluate the examination process by including an automated pre-examination search, and whether the inclusion will improve quality and efficiency of examinations.

The program (ASAP!) will conduct an automated search for original, noncontinuing, nonprovisional applications. The automated search results will be sent to the applicant and will provide an earlier communication regarding potential prior art issues. Under the pilot program, applicants will not be required to respond to the search results.

However, the search results may provide an opportunity to the applicant to file a preliminary amendment in an effort to place the application in a stronger position for allowance. Alternatively, the applicant may wish to file an express abandonment and obtain a fee refund in view of search results that indicate a lack of patentability.

Recently, the U.S. Patent Office has announced that it is waiving the fee requirement for any petition to participate under 37 C.F.R. 1.182 filed after March 23, 2026. This should enable self filing entrepreneurs and inventors to take advantage of this new program for free!

DIY Patent Searches: Good Luck with That

DIY Patent Searches: Good Luck with That

Recently I’ve found websites and blog posts promoting your ability to conduct your own patent search.  Unless your invention is extremely straightforward, I would not recommend doing that. 

The U.S. Patent Office was created in 1802.  As such, issued patents were organized by categories or classes and subclasses.  As innovation has evolved, the categories of classes and subclasses has evolved and changed considerably.  Unless you are extremely familiar with the patent records organization, you are better off spending your money on a professional searcher who will find all of the relevant categorical nooks and crannies.  Often times a material, process or structure in your invention may have applicability in areas you have not considered.  These need to be identified and pursued in order to obtain a full and thorough search. 

Patentability must be based on a complete search to have value.  If not, you are spending good money after bad by investing in the preparation and filing of a patent application based on incomplete patent search results.  You are better off knowing that your invention is unpatentable than spending money on the preparation and filing of a meaningless application.  In addition, your application, and particularly your claims, can be tailored to that patentable space defined not only by your invention but by the relevant prior art found in a good search.
