Perfected in that context means recorded officially. Something can be more perfected by being officially recorded first before someone attempts to (or actually does) "perfect" (officially record) a contrary thing.
I am not your lawyer and you are not my client. Free advice here is without recourse and any reliance thereupon is at your sole risk. This is done without compensation as a free public service. I am licensed in IL, MO, TX and I am a Reg. Pat. Atty. so advice in any other jurisdiction is strictly general advice and should be confirmed with an attorney licensed in that jurisdiction.
Also not an intellectual property question that needs to be re-categorized, with another confused asker including the kitchen sink of keywords for their question.
Avvo doesn't pay us for these responses, and I'm not your lawyer just because I answer this question or respond to any follow-up comments. If you want to hire me, please contact me. Otherwise, please don't expect a further response. We need an actual written agreement to form an attorney-client relationship. I'm only licensed in CA and you shouldn't rely on this answer, since each state has different laws, each situation is fact specific, and it's impossible to evaluate a legal problem without a comprehensive consultation and review of all the facts and documents at issue.
Perfection in the contexxt of a secured transaction is the legal step necessary to make the security interest in the collateral enforcable. For most collateral other than real estate, perfection refers to filing a UCC-1 form with the Secretary of State for the state in which teh collateral is located. This is a public fililng showing that can be searched on line. That prevents the debtor from selling the collateral without first paying off her debt.
