An old friend of mine used to work as an engineer in the IP protection
department (or something like it, staffed mostly with lawyers) for a
big name company in Singapore. I don't remember which company it was,
probably Texas Instruments or Intel. Anyway, from what he told me, his
job is to reverse engineer competitor's products to find out if they
violated any of his employer's IP.
DofBC: Is there such a thing as a search warrant to check for copied
tech?
There are a number of reverse engineering firms in Taiwan who'll do a
3D scan of a product for you by slowly shaving the product and taking
a picture of the cross section. This is how people reverse engineer
electronic bits in epoxied packages. The company my friend worked for
was big enough that they did this in-house. But even smaller companies
can do this by outsourcing to Taiwan.
DofBC: Schematics just make it easier to check for patent
infringement.
Reverse engineering is almost never done by looking at schematics. For
one thing, the most important part is usually a black box in the form
of an ASIC. Reverse engineering is hard work. But like I mentioned
above, there are companies out there that does it for a living. If you
suspect that your competitor is stealing your IP you can simply send
that product to Taiwan to have it broken down and analysed.
