When does the patent US4984987 expire?
Does the CE Approved CPR and AED Training device infringe this patent?
The original filing date is November 9, 1989. A Utility patent is valid for a term of 20 years, which means this patent expired on November 9, 2009 and is no longer valid. The link you posted to does not infringe on this particular patent, but it might be infringing on other patents.
Edit: Eric pointed out that this patent was pre-1995 and there for only valid for a period of 17 years from the issue date.
