Trade secret: Business information that is the subject of reasonable efforts to preserve confidentiality and has value because it is not generally known in the trade. Such confidential information will be protected against those who obtain access through improper methods or by a breach of confidence. Infringement of a trade secret is a type of unfair competition.

Utility model
A utility model is a statutory monopoly granted for a limited time in exchange for an inventor providing sufficient teaching of his or her invention to permit a person of ordinary skill in the relevant art to perform the invention. The rights conferred by utility model laws are very similar to those granted by patent laws, but are more suited to what may be considered as "incremental inventions". Terms such as "petty patent", "innovation patent", "minor patent", and "small patent" may also be considered to fall within the definition of "utility model".

Intellectual industrial property
Industrial property legislation is part of the wider body of law known as intellectual property. Intellectual property is usually divided into two branches, namely industrial property and copyright. The broad application of the term “industrial” is clearly set out in the Paris Convention for the Protection of Industrial Property (Article 1 (3)): “Industrial property shall be understood in the broadest sense and shall apply not only to industry and commerce proper, but likewise to agricultural and extractive industries and to all manufactured or natural products, for example, wines, grain, tobacco leaf, fruit, cattle, minerals, mineral waters, beer, flowers, and flour.”

Community patent, also known as the European Community Patent or EC patent and sometimes abbreviated as COMPAT is a patent law measure being debated within the European Union, which would allow individuals and companies to obtain a unitary patent throughout the European Union. The Community patent should not be confused with European patents which are granted under the European Patent Convention. European patents, once granted, become a bundle of nationally enforceable patents, in the designated states. This can be expensive for the patentee in that enforcement must be carried out through national courts in individual countries, and for a third party in that revocation cannot be accomplished centrally once the nine-month opposition period has expired.
