You don't understand how patents and trademarks work do you? It is the law that David has to provide the patent number on any device he sells if he is claiming it has a patent, otherwise he is in violation. All patents that are approved have a 7 digit serial number. Without it, he has a pending status and there will be an 11 digit number, therefore it is not held under the same law as a patent. Also it is not pursuant under any patent protection laws. Patents are only good from the day they are issued, they are not retroactive. If he doesn't have a 7 digit number, he doesn't have a patent.
Trademarks have to be the exact marking. The only trademark registrant number he has provided is in regards to a name that is irrelevant to the issue at hand. Asking for something relevant is not mundane, it is actually seeking who is telling the truth here. If he is claiming trademark infringement, then he must provide that approved trademark serial number. Common law trademarks, ones that are not registered do not have the same benefits of ones that are. Under the stanton law, I believe is the name, someone with a common use trademark that has not been registered is not able to file suit or claim damages for trademark infringement.
Though you have a point, instead of anyone harassing anyone, maybe we all can utilize the internet for some other beneficial needs. Google the laws, and rights of those who have pending statuses. Actually, it is David who could be sued, if he tries to harass anyone about a clone, when he has a patent pending, not a registered patent, or registered trademark. If he offers a platform and knows that others are harassing an individual, he can also be held liable. This forum has proof of that. He is instigating the harassment. This forum is suppose to be about the ELA. Instead it is 3/4 about a person that isn't even be on this forum and can't defend themselves. Sounds like harassment to me, and since it is clear David knows about it, that holds him liable.
Also I am sure if say someone on this forum was harassing CC by trolling her spread sheets. Well google keeps a record of every single ip address. Even though she may delete a certain line on the spread sheet, all that information is still retained on google's site. Therefore if push came to shove, I am sure that extracting all that info, along with the ips would be very easy to do.
Same with making false reports about peoples facebook accounts.
