us patent boolean search

You’ve been a good friend and a necessary evil for the past 2 decades to me. Grep expressions can be concatenated to form new meaningful expressions whose match is the concatenation of the respective matches—an intuitive result. Additional optimizations are described when users need to search for any one of a list of text patterns. Another technique you can use to iterate your search is to give each of your terms a weighting factor. For example, the asterisk is not supported on LinkedIn. to further develop patent legal status databases and widen the participation of countries in data sharing. As can be seen the Matched Text for any Search Pattern other than an exact literal one, depends on the found instance. and means that the search is to find an instance of the word “Nisus” not immediately followed by the word “Software”. Shorthand: :+, (xxxi) 0 or 1 Means the preceding character, wild card or parenthesized expression is to occur zero or one times and assures the largest possible number of occurrences for a match (that is, longest match). Such an implementation requires the user to maintain that separation (between GREP and Boolean parts of the search expression) which means using different Boolean and GREP parentheses and distinguishing between the GREP Or and the boolean OR. Boolean to Extended GREP Conversion Table When the resulting ERE is passed to the ERE parser, that distinction is maintained by that parser. (xx) European Includes all special characters and characters with diacriticals. Does not close a reference. If we wanted to designate \s literally we would write \\s. Contact us; LOGIN. This number is not assigned by the USPTO and can be any combination of numbers and letters. This would limit the search results to only those documents containing the two keywords. For example regarding the target, it would be useful to specify that the words searched for must all be within a sentence, or perhaps within a paragraph, rather than, as at present, anywhere in the document. Simulating the NOT operator is not possible without additional features. Search one site (like wikipedia.org) or limit your results to a domain like .edu, .org or .gov. You’ve probably heard of the saying, “you only get out of it, what you put into … Saved from patft.uspto.gov. You can now access a wider variety of patent-specific documents page. dismiss this message . The PowerFind Pro engine, implemented in Nisus Writer, is an extension of the Unix GREP and includes only one boolean operator: the “OR.” The “AND’ operator can however be simulated by using the “OR” and the other features of PowerFind or PowerFind Pro. Such a high level programming tool is a very valuable invention for use in taxonomy because of the ease with which changes can be made in the categorizing Search Patterns. When parentheses do not intervene, the order of precedence of the Boolean Operators in evaluation is as follows: NOT means a negation of the Search Pattern which follows. Patents can be searched by number, simple text search, Boolean text search in one or two patent fields or advanced text search in any searchable field. Global Dossier provides access to the file wrapper of a patent application, wherever it is made available by the patent authority in question. The user is presented with only one class of parentheses: the GREP type. OR is particularly useful for synonyms, like ‘bank OR finance OR financial.’ A OR B | A ∪ B NOT. Advanced search engines allow a full “logical” or boolean search, by which is meant that words or phrases can be combined using the boolean operators “AND”, “OR”, “NOT”, and NEAR. }:) ‘OR’ – The OR operator is used to search … Defines any character in the user defined set. Shorthand: {dot over (a)}, (ix) Any HTML Tag. or using a more understandable description NOT z NOT IMMEDIATELY FOLLOWED BY a, which could also be designated as: once concatenation of a and z is defined. The mixed boolean-GREP expression entered by the user is converted by the Pre-Processor to an Extended Regular Expression (using the replacements detailed in the GREP Table) which is then processed by the Extended GREP Engine. Such a set of boolean operator features gives the user greater control of the text being searched. The NOT operator excludes unwanted terms from your Google sourcing search. The usual meaning, for which we use the word AND, is a search for the two conjoined Search Patterns, regardless of the order of their occurrence. Free patents online. Rely on a good relevancy algorithm to bubble the best matches to the top of the list. Create collections, alerts … A pre-processor is described which will convert mixed Boolean-GREP expressions into equivalent pure GREP expressions enabling existing GREP search technology to be used to implement this invention. Shorthand: {m,}, (xxxvi) From m Times Short Means the preceding character, wild card or parenthesized expression is to occur “m” or more times and assures the shortest possible match.
