U.S. and European patent strategy for thermal energy storage.

A thermal energy storage company needed coordinated patent prosecution across the U.S. and Europe — without sacrificing claim breadth to EPO pressure to narrow.

// WHY A CLEANTECH PATENT STRATEGY MATTERS
Market positioning
Patent protection helps energy startups differentiate their technology in a crowded field.
Global expansion
Coordinated filings across jurisdictions ensure IP protection as companies scale internationally.
Portfolio flexibility
Strategic filings and portfolio management preserve options for future innovation.
// OUR APPROACH

How we ran the matter.

01
U.S. utility application
Lynch LLP prepared a utility patent application focused on the client's core thermal energy storage system. Claims were drafted to emphasize technical configurations and system-level improvements.
02
European filing strategy
When the European Patent Office proposed narrowing claim language, we pushed back — avoiding overly specific configurations that could limit future protection. The team preserved broad claim scope and prepared for potential divisional filings to capture additional embodiments.
03
Portfolio planning
Lynch LLP tracked maintenance deadlines and advised on continuation filings to extend protection and adapt to evolving product designs.
// RESULTS

What we delivered.

  • Maintained broad claim scope in Europe and continued prosecution in the U.S. despite EPO pressure to narrow.
  • Preserved options for future filings and positioned the company for long-term IP protection across key markets.
// KEY TAKEAWAYS
01
Drafting for growth — claim scope drafted to leave room for future innovation.
02
Coordinate globally — align U.S. and international filings to ensure consistent protection.
03
Stay proactive — monitor deadlines and plan for continuations to keep your portfolio adaptable.
