Il brevetto del prototipo è stato rubato da un concorrente.

Questions & Answers about Il brevetto del prototipo è stato rubato da un concorrente.

This lesson is about the reportative conditional. How would we change this sentence to say the patent was allegedly stolen?
To express unconfirmed information, you need the past conditional (condizionale passato). You would change the indicative passive verb è stato rubato (it was stolen) to sarebbe stato rubato (it was allegedly stolen). Journalists use this form frequently to report crimes or scandals before the facts are legally proven.
Why does this sentence use è stato rubato instead of just ha rubato?
This sentence is in the passive voice. The active version would be un concorrente ha rubato il brevetto (a competitor stole the patent). To make it passive in the passato prossimo tense, we use the auxiliary verb essere conjugated in the passato prossimo (è stato) followed by the past participle of the main verb (rubato).
Is there a specific reason we use da for "by" a competitor?
Yes, in Italian passive sentences, the preposition da is always used to introduce the agent of the action (the person or thing actually doing the verb). Just like "by" in English, da un concorrente tells us who performed the theft.
Why is "patent" translated as brevetto? Can I use the word patente instead?
No, they are false friends! In Italian, la patente almost always refers to a driver's license (la patente di guida). When talking about intellectual property or the exclusive rights to an invention, you must use the word il brevetto.
