Impinj review

Litigation-tested RAIN RFID estate, access on Impinj's terms

Verdict

RAIN RFID tag chips, reader chips, readers and software that wirelessly connect everyday items so businesses can identify, locate and protect them. Licensing posture: No open licensing program on their site, but IP is visibly part of the business: a 2024 settlement with NXP cross-licenses each company's patents and terminated all pending litigation.

What customers praise

A genuinely focused portfolio built around one protocol family and its silicon, and it survived the hardest test there is: multi year litigation against NXP that ended in a settlement cross-licensing both companies' patents.

What customers criticise

An outsider has no stated door in: no published program, rates or contact for taking a license, and the litigation history suggests access happens on Impinj's terms, through standards participation or a courtroom.
