Let me re-phrase. Is it your opinion that Ettus' products comply with
the OHSW definition?
Here I can find only pdf files for schematics:
Does this comply with this statement in clause (1) of OSHW definiton?
"The documentation must include design files in the preferred format
for making changes, for example the native file format of a CAD
program. Deliberately obfuscated design files are not allowed.
Intermediate forms analogous to compiled computer code — such as
printer-ready copper artwork from a CAD program — are not allowed as
It doesn't seem that OSHW definition requires you to publish PCB
layouts, so schematics only look fine. But it asks you to publish your
design files in a editable format.
Another (unrelated) question. The OSHW definition says:
"Under U.S. law, and law in many other places, copyright does not
apply to electronic designs. Patents do. The result is that an Open
Hardware license can in general be used to restrict the plans but
probably not the manufactured devices or even restatements of the same
design that are not textual copies of the original."
Does it mean that schematics *is* protected by copyright?
