Term ends no later than Oct 17, 2036 · Medium confidence
20-year base term ends Sep 15, 2036
In force on USPTO's status record and by its fee record. A terminal disclaimer on file may shorten this term, possibly to a date already past; its reference document is unresolved, so the date above is an upper bound and no earlier date is guessed.

How we calculated this date
One row per rule, each showing its own input and what it did to the date. A step we could not verify says so instead of resolving itself.
| Step | Input | Date after this step | Confidence |
|---|---|---|---|
| Base term, 20 years from filing | Clock starts Sep 15, 2016, when application PCT/IL2016/051025, the earliest non-provisional in its chain, was filed (this one was filed Apr 17, 2020) | Sep 15, 2036 | High confidence |
| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | +32 days, USPTO patent term adjustment record | Oct 17, 2036 | High confidence |
| Terminal disclaimer cap | Disclaimer on file (approved), reference document not resolved | no cap applied, and none guessed | Medium confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 1 of 3 maintenance fees paid | In force | High confidence |
| Computed term end | The steps above, in order | no later than Oct 17, 2036 | Medium confidence |

What's changing
Oct 2036
Term ends no later than Oct 17, 2036. Maintenance fees still fall due before then

A terminal disclaimer is on file and its reference is not resolved. No cap is applied and none is guessed
Note
The 32 days of patent term adjustment (USPTO delay) are read from the USPTO record, not recalculated by us
Open question
A terminal disclaimer is on file (approved) and its reference document is not resolved. A disclaimer would cap the term earlier than Oct 17, 2036. We will not guess the cap.

How we rank
Every date shows its work: the base term, any term adjustment or extension, any disclaimer cap, and the maintenance fee record, each with a confidence tier. How this record was built
This computed term ends no later than the date shown; an unresolved terminal disclaimer may end it earlier. Related patents and pending applications may cover overlapping subject matter.
In force means the term is running and no lapse is on record. It is not a finding that the patent is valid.
