	Patent classification
		Patent classification schemes are used to organise and index the technical content of patent specifications so that specifications on a specific topic or in a given area of technology can be identified easily and accurately.
		Patent classification schemes are constructed and maintained by and for patent examiners and their primary purpose is to help the examiners in their work.
		The IPC codes, which act as an index to the subject matter of the patent, are printed on the front page of a patent specification and are always identified by the INID code 51.

	Concordance Between the U.S. Patent Classification System (USPC) and the International Patent Classification (IPC) ...
		When a particular classification rule is stated for classifying inventions within the groups of an IPC subclass, that particular rule is applicable and the general classification rules are overridden.
		The only exception, is that IPC subclass or group titles that specify only a process, a product, or an apparatus category of invention may also include another category within their scope for its specific subject matter (e.g., a group for "hats" could also take "making hats").
		The last general classification rule is applied when a patent document claims diverse technical inventions covered by either (a) two or more coordinate subgroups under a single main group or (b) plural main groups.

	International Patent Classification - Guide
		The text of the first edition of the Classification was established pursuant to the provisions of the European Convention on the International Classification of Patents for Invention of 1954.
		It is recommended that published patent documents classified in accordance with a given edition of the Classification bear an indication of that edition in the form of a superscript Arabic numeral, printed immediately after the abbreviation.
		The Classification represents the whole body of knowledge which may be regarded as proper to the field of patents for invention, divided into eight sections.

		The patent classification is your key to technical information, especially when "words are not enough".
		The importance of a patent classification has not diminished in the era of electronic access even though classification was first to exist.
		In the days of manual searching, classification was the only means of organizing documents in a way that enabled search of earlier, similar inventions from the vast collections of patent documents.

	Concordance Between the U.S. Patent Classification System (USPC) and the International Patent Classification (IPC) ... (Site not responding. Last check: 2007-10-21)
		Although the concordance often seems to infer that the concorded classifications are equivalents, differences in placement rules and the interpretation of the scope of the subject matter claimed between the two systems makes such a one-to-one translation rarely attainable.
		When only an IPC subclass, e.g., A01B, is listed for a US classification in the concordance, the user should peruse the entire IPC subclass to find the most appropriate, complete classification, e.g., A01B 1/00.
		Users of this Concordance are encouraged to read the linked web page, Classifying Within The International Patent Classification System (IPC), which provides information on the particular differences between the USPC and the IPC and presents some basic steps in classifying documents into the IPC.
