What You Will Learn
- 1Manufacturers often invent more on the shop floor than in the product itself
- 2Tooling, fixtures and assembly sequences can be patent or trade secret candidates depending on visibility
- 3Trade secrets only hold value when the company actually protects them
- 4Field service fixes and warranty data are an underused source of new inventions
- 5Expired patents can be a useful design resource, with counsel reviewing any plan to rely on them
Manufacturers invent constantly and file rarely. Improvements live in tooling, fixtures, assembly sequences and setup sheets, and most never become a disclosure. Some of those improvements save more money each year than the product features sales talks about.
Inventions on the Shop Floor
- Tooling and fixtures: designs that cut setup time or improve repeatability
- Assembly methods: sequences that reduce defects or labor
- Inspection: measurement and sensing approaches that catch problems earlier
- Materials handling: ways of moving, joining or finishing parts
Where to Look
- Continuous improvement and kaizen records
- Scrap and rework reduction projects
- Engineering change orders with a clear before and after
- Supplier collaboration on new parts or processes
Ask for the biggest savings
Ask manufacturing engineers which three changes saved the most time or scrap last year. That list is often a better starting point than the product roadmap.Patent or Trade Secret
Process improvements that cannot be observed from the finished product are often discussed as trade secret candidates. That only works if the company protects them through access controls, documentation and confidentiality agreements. Improvements visible in the product, or in equipment you sell, may be better patent candidates. Counsel should confirm each call.
Field Feedback
Warranty returns and field service reports show where products struggle in real use. When a technician improvises a fix that works, there may be a better design hiding in it. A quarterly review of recurring fixes with engineering turns that feedback into documented concepts.
Building the Portfolio
- Run a prior art search before investing in a filing
- Use research into expired patents as a design resource, with counsel reviewing reliance on them
- See the mechanical patents guide for product-side inventions
