Patents, like any security documentation, are characterized by an abundance of not only characteristic terms, but also archaisms that are no longer used outside the scope of security activities at this point of time. This should be taken into account when doing English to Russian patent translation. A number of words have different established meanings depending on the section of the patent wherein they are used.

Typical phrases, cliches, used in patents are not always translated English to Russian literally or close to it. In another language there are often only semantic synonyms for them. Patent documentation in different languages, when translated from English to Russian, has its own lexical features. For example, the English patent language is characterized by redundancy. It is expressed in the use of synonyms, nouns and verbs at the same time.

When it comes to Russian patent translation, a phrase in English that some invention leads to an increase in the efficiency of a process limitation, the variant would retain improvement and increase, both within the framework of "increase". Accordingly, when translating into English, the translator needs to artificially create this tautological text and remove it from English into Russian, on the contrary, translating synonyms into English.

Also, Russian patent translations are characterized by the construction of sentences in first person; constructions are unusual for Russian documentation, so the phrase must be reformulated to preserve the meaning. In other words, rewriting is allowed as part of Russian patent translation that does not affect the meaning of the source text.
