Yes, companies typically file life-extending patents around the core patent (drug companies are infamous for this). However, if another party comes up with a way to use the core without infringing on the extensions, it's completely fair game. Sawstop has already seen the handwriting and has committed to release the core technology to public domain if/when legislature calls for implementation. This is a hallow gesture at best since it is probably about to expire.
SawStop To Dedicate Key U.S. Patent To The Public Upon The Effective Date Of A Rule Requiring Safety Technology On All Table Saws

TUALATIN, OREGON, Feb. 28, 2024 — Today, in response to proposed rulemaking regarding table saw
safety by the U.S. Consumer Product Safety Commission (CPSC), SawStop committed to dedicate U.S.
Patent 9,724,840 to the public upon the rule’s effective date.
The intent of the proposed rule is to prevent the
thousands of amputations and hospitalizations that will
continue to occur without industry-wide action.
“We work to protect and inspire all woodworkers, from novice hobbyists to professional craftspeople.
Opponents of the proposed rulemaking have identified this patent as their key obstacle to offering safer
saws,” said Matt Howard, CEO, SawStop. “We invest heavily in safety innovation, and our patents have
real value. Even so, we will not allow this patent to be an obstacle to a safer future. To that end, SawStop is prepared to dedicate this ‘840 patent to the public upon the effective date of a rule requiring active injury mitigation technology on all table saws. Although such a rule is likely many years away from an effective date, we at SawStop are determined to seek a win-win balance between our mission and our business responsibilities.”
Actually their patent does not expire until 2034. The patent only issued after litigation where the Court of Appeals for the Federal Circuit overturned the patent office's rejection. The litigation took ten years and Sawstop is allowed to regain the term of the patent.
Wow - that's interesting!
