Non-obviousness

One of the three core requirements for a utility patent. An invention is non-obvious if someone with ordinary skill in the relevant field could not have easily combined existing knowledge to arrive at the invention. Non-obviousness (35 USC § 103) is the most frequently litigated and most difficult requirement to satisfy — the line between "obvious" and "not obvious" is contested in almost every patent case.

Non-provisional application

The "full" patent application examined by the USPTO — as opposed to a provisional application, which is a placeholder. A non-provisional application must include a complete specification, drawings (if necessary), at least one claim, and payment of the filing fee. The non-provisional is what gets examined and, if allowed, issues as a patent.

Novelty

The requirement that an invention must be new — not previously known, used, or disclosed publicly anywhere in the world before the filing date. Under the America Invents Act (2013), the US uses a first-to-file system: the applicant who files first gets priority, regardless of who invented first. Even the inventor can destroy novelty by publicly disclosing the invention more than a year before filing.

Abstract

A brief summary (300 words or fewer) that appears at the top of every patent. The abstract describes what the invention does in general terms. Legally, it has almost no weight — courts use the claims to determine what a patent covers, not the abstract. The abstract is useful mainly for quickly scanning patents during a prior art search.

Anticipation

A legal standard for rejecting a patent claim. If every element of a claim was already disclosed in a single prior art reference — in a patent, article, or product — the claim is "anticipated" and cannot be patented. Anticipation requires a single source to contain every element; if you need two sources, it's an obviousness argument, not anticipation.

Appeal

A request to have a patent examiner's rejection reviewed by a higher authority. After receiving multiple rejections, an applicant can appeal to the Patent Trial and Appeal Board (PTAB) within the USPTO, and from there to federal court. Appeals are expensive and slow, but sometimes necessary when an examiner applies the law incorrectly.
