Classification(s)
Claims describe what makes the invention unique. They establish the boundaries or scope of an invention and are the standard by which patent rights are measured.
To infringe on a patent is to make, use or sell an invention that has all of the elements in one of the claims or closely fits the description in the claims.
The entity (often a company or an organization) to whom the rights of the patent are granted.

Patent numbers help identify the type of patent you are reading:P = plant patents (e.g. PP04979)D = design patents (e.g. D523255)No letter = utility patents (e.g 6026316)
Abstract
Utility patents are issued for new and useful inventions and processes, machines, manufactures, compositions of matter, or a new and useful improvement to existing inventions.
Approximately 90% of the patent documents issued by the USPTO in recent years have been utility patents, also referred to as “patents for invention."
Patent number
List of related patents and other publications to acknowledge prior art and help research. It cites patents from the US and other scholarly sources.
In the United States, patents are granted by the United States Patent and Trademark Office (USPTO) and are valid only within the United States.
A patent granted by the United States Government gives the inventor the right to exclude others from making, using, selling, importing, and offering an invention for up to 20 years.
A patent makes specific claims that describe the scope of the invention and what makes it unique.

Patentability
Sapphire component with residual compressive stress US 20140193606
Design patents are issued for a new, original, and ornamental design for an article of manufacture.
Non-obviousness
Patents are a great source of technical information for design and academic research.
They contain descriptive and useful information on inventions not necessarily available anywhere else.
Patents aim to promote innovation by financially rewarding patent holders.
Design patents
Inventions must differ in some way from all previous technological developments available anywhere in the world. This is also known as prior art.
Novelty
Why are patents important to your research?
Plant patents are issued for new and distinct plants. Both invented plants and discovered asexually-reproduced plants are eligible for patents.
Examples include mutants, hybrids, and newly found seedlings.
Plant patents
Inventions must serve a purpose. They cannot merely be aesthetic creations.
The person (or people) who files the patent; the creator of the invention.

Inventor(s)
Visual representations of the invention, representing every feature described in the claims. They must be in accordance with current USPTO rules.
Short, simple title of the invention.

The invention must differ from existing disiplinary knowlege in a way that would not occur to a typical person in the discipline.
Three characteristics of patentable inventions
It’s important for research to be able to recognize the parts of a patent.
The example images below are from an actual utility patent. It can be opened here: Method and apparatus for use with MR imaging (US 6026316A)
References
Describes the invention in sufficient detail so that anyone of ordinary skill in the same technical field can understand it. It includes:
a discussion of the related prior art (previously issued patents and other publications)a description of the figuresthe "preferred embodiment" of the invention (the implementation of the invention thought to be the best when the patent is filed)the claims
Patents are classified by number. Patents of a similar type will share classification numbers, making it easier to find related inventions.
