</div>company B is required, under the ODbL, to provide an offer of their<br>
derived database (or a diff, etc...).<br>

</div>if you suspect that someone is using a derived database, and isn't<br>
making an offer of it, you are suspecting that they are in breach of<br>
the ODbL. this can be tested by asking the company and, if they don't<br>
provide a satisfactory response, legal proceedings could follow.<br>

this is similar to the AGPL. if you suspected that someone was<br>
distributing or allowing "users [to] interact[...] remotely through a<br>
computer network" with a derivative version of AGPL'd code, you could<br>
ask them where the corresponding offer is and, if they don't provide a<br>
satisfactory response, legal proceedings could follow.<br>
