Morphology

patent + troll

The compound pairs the clear noun 'patent' (a legal right) with the metaphorical sense of 'troll' (a predatory or nuisance actor), so a learner can infer it denotes someone who causes trouble involving patents. However, the precise specialized meaning—acquiring and enforcing patents primarily to profit through litigation rather than to produce inventions—is a domain-specific, metaphorical extension that is not fully predictable without prior exposure.

Etymology

The name patent troll may come from the image of a troll hiding under a bridge to demand money, with patent meaning a legal right to an invention. One popular story says these people or companies keep patents and sue others or demand fees, so the name now means 'a person or firm that uses patents mainly to get money through lawsuits instead of making products'.
