Protect Your Mechanical Inventions With a Mechanical Patent Attorney
Mechanical innovation moves fast, and so does everyone trying to copy it. Sleman & Lund LLP brings more than twenty years of patent experience to the engineers and product developers building the machinery, systems, and components that industry runs on.
Why Should You Hire an Attorney to Obtain a Mechanical Patent?
Mechanical inventions rarely live in one part. They're assemblies of linkages, tolerances, materials, and manufacturing steps, and the real innovation is often buried in how those pieces work together rather than in the finished product alone. A mechanical patent attorney who understands engineering can spot that distinction and draft claims around it, rather than around the obvious surface feature.
An experienced mechanical patent attorney can help you evaluate your invention, identify where the protectable elements actually sit, and build a portfolio that grows as the design evolves.

What Our Client Says
I literally had 24 hours to respond to an Office Action. I explained my status with Peter and with no hesitancy took on the challenge. Not only did he accept the challenge he satisfied the USTPO with the info they needed within the time left, he and his team knocked it out of the Park! So, if you want a no-nonsense Patent Attorney Peter & PatentSpace IS the place!
Paul Ugactz
Peter is personally invested in the success of his clients. He takes the time and makes the effort to ensure clients understand the strategy into what concrete steps clients can take to develop their ideas into a patented product. Peter effectively combines noteworthy analytic and interpersonal skills into his approach to problem-solving, product/process development that is truly effective. I found him to be a strong collaborator who had an equally strong commitment to his clients. I unreservedly recommend Peter and his firm.

Frequently Asked Questions
What does a mechanical patent attorney actually protect?
A mechanical patent attorney protects the structure, the assembly, and often the method of manufacturing behind a device. A single mechanical product can carry several separate patentable elements, such as a linkage, a fastening method, and a material choice.
Do I need a working prototype before I file a patent?
No. Many of the inventions our mechanical patent attorneys have helped patent began as sketches, CAD models, or descriptions of improvements to an existing machine. What matters is that the invention is described in enough technical detail to support a patent application, which our attorneys can help you develop.
How is a mechanical patent different from a design patent?
A utility patent on a mechanical invention protects how something works; its function, structure, and mechanism. A design patent only protects how something looks. Many mechanical clients need both, and we help sort out which protection actually fits the invention before filing.
Do you work with individual engineers, or only manufacturing companies?
We represent everything from established manufacturers to individual engineers and inventors filing their first patent.
How long does it take to patent a mechanical invention?
Timelines vary with the complexity of the device and the current USPTO backlog, but most utility patents for mechanical inventions take 1 to 3 years from filing to grant. We give clients a realistic estimate upfront based on the technology and file accordingly.
