For complete coverage of the subject matter, you would spend 6.5 years executing these searches if each took only 5 minutes, which is optimistic. 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. It is likely that only the first hundred or so documents will be truly relevant. You can also get insight about what your competitors are developing. Many such search engines appear to allow for some synonyms of the words typed and are largely word based, that is, unless the text typed by the user is placed in quotes (or designated as literal in some other way) the search assumes a match if the typed words appear in a document in any order and in most search engines, with the implied “OR” between every word and the next one. However simulating an “AND” is not very convenient. Delisted Patents . Save search so you can apply it again in the future. You’ve probably heard of the saying, “you only get out of it, what you put into … The equivalent (postfix) Extended Regular Expression operator is designated as % {!}. Each pass through the Pre-processor replaces one Boolean operator with an equivalent GREP expression, and so each time modifies UE into the “Current Expression” or CE until that expression becomes entirely an Extended Regular Expression and so can be passed to an Extended Grep Engine. It also includes a sequences of digits, commas and period when not followed by a space, tab or return. WARNING: Before conducting your search, you must understand the following: (1) what the database includes; (2) … The user defines a set of simple or complex Search Patterns for each pre-defined category. This is the same as the above but with the shortest possible match. Shorthand: {n,m}, (xxxviii) From n To m Short Means the preceding character, wild card or parenthesized expression is to occur at least “n” times but not more than “m” times and assures the shortest possible match. Does not begin a reference. Shorthand: [{circumflex over ( )}]. Boolean search writing is a skill that top recruiters need to know in order to get meaningful candidate search results from a wide range of software, including LinkedIn, various job portals and Google. Owners (US) Document Types. Classification search in Espacenet helps you to find suitable classification symbols for your search, and then to apply in the search itself. For example, to find documents containing the word “education” and either the word “Internet” or “networking” or “network” but not containing the words “school” or “college” the user would type the advanced search expression: education AND (networking OR network OR Internet) AND NOT (school OR college). Shorthand: \v, (xxiii) Space The literal typed space. Aug 2, 2005 Grant Date; N/A app pub date; Jul 5, 2000 filing date; Jul 5, 2000. priority date . Shorthand: \f, (xxvii) 0+ Means the preceding character, wild card or parenthesized expression is to occur zero or more times and assures the largest possible number of occurrences for a match (that is, longest match). In a mixed Boolean-GREP environment, the GREP Or binary operator has the same meaning as the Logical “OR” operator except that in most implementations it is higher in precedence than the logical “OR.” As is explained below, the pre-processor replaces the Logical “OR” with the GREP “Or.” To avoid confusion, the user is not allowed direct access to the GREP Or, providing only one “OR.” The Logical “AND” and related binary operators can be synthesized entirely from GREP expressions. Recent documents: US Patents US Applications US Design Patents Miscellaneous: Crazy Patents University Patents Chemical Patents New Computers: Permitting Access Electrical Computers Software: Finance Dynamic IR Card Processing Data Processing Data Analysis … Don’t forget, as technology evolves, and the lexicon changes, you’ll have to update your search to include the newer terms. Patent Center. The “+” following that means that the repeated text may occur one or more times. For example the following simple regular expression will find a sequence of digits at the beginning of a paragraph: where “{circumflex over ( )}” stands for “the beginning of a paragraph,” “:d” stands for any digit, and the “+” stands for “occurring one or more times” referring to the digit. When the user chooses this feature from a menu, a special window opens allowing the user to enter the list (by either typing or choosing from a vocabulary list) without the need to add the OR boolean operator between the words. Justia Patents Particular Algorithmic Function Encoding US Patent for Converting a boolean masked value to an arithmetically masked value for cryptographic operations Patent (Patent # 10,871,947) Converting a boolean masked value to an arithmetically masked value for cryptographic operations . Contact Us. Patent legal status. The definition of a word includes a sequence of alphanumeric characters, excluding any characters which are word separators. The Search Pattern is the text pattern, defined by the user (either using special symbols, or choosing them from lists or menus) which the search engine is to search for, within the Search Target of the text. This application claims the benefit of provisional application Ser. In English there are two characters, the comma and the period, which can be part of a number-word but not part of a letter-word. At that point the right operand is B which excludes the last closing parenthesis, if present, when condition (c) is satisfied, and excludes any boolean operator which caused condition (b) to be satisfied. Decide if any terms must exist in the documents, or if any are optional, or can be grouped as required synonyms. Shorthand: :.;; Search for: PatSeer patseer 2021-01-14T09:32:35+00:00 > Free Trial. In my role as a partner at, I talk to patent searchers every day whose search skills range the gamut from novices to 20+ year salty dog gray beard patent research veterans. The pre-processor, in one or more passes, modifies UE converting it entirely to an Extended Regular Expression. This is typically not too difficult. Re-set the parenthesis count to zero. People might use different words to say the same thing. So one possibility where the two expressions are combined would be: This specifies the contents of the target independently of the positions of the matches to the boolean “a” or the boolean “z”. Now, I know it may sound like an unexciting topic if you are an experienced patent searcher, but in the following context, it may just blow you away, and possibly change the way you approach your job. The full set of extended Regular Expression symbols includes the following: 1 Wild Cards & Expressions. 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. The second Search sub-Pattern for the company name is defined more simply as: The minus following the comma means the comma may occur zero or one time (which means it need not be there). Patentveröffentlichungen suchen, Patentdokumente maschinell übersetzen lassen, den Fortschritt von neuen Technologien verfolgen, Lösungen für technische Aufgaben finden, die Entwicklungen Ihrer Mitbewerber beobachten. Some of these include applications to automated Taxonomy, the categorization of text documents. The Orange Book downloadable data files are updated monthly. (Usually NEAR means within 10 words of each other, and this number of words is not under users control.). Then split CE=CE1+A Op B+CE2, where “Op” is the Boolean binary operator and A and B are respectively its left and right operands. A paragraph ends on a Return (or new paragraph character) or the end of text and begins after a return or at beginning of text. This definition does allow such objects as, for example, “23,34.89.90,80” to be treated as words, although that may not make sense. This example Search Pattern could not be defined as easily in any currently existing search engine. Mar 20, 2017 - US Patent Full-Text Database Boolean Search. WESTINGHOUSE AIR BRAKE COMPANY, PENNSYLVANIA, Free format text: An example of a text pattern matching engine, implemented as part of a Macintosh word processor, is the PowerFind™ and PowerFind Pro features within the Nisus Writer word processor for the Macintosh, first published as a software product in January of 1989 under the U. S. registered trade name “Nisus” and in more recent versions re-named “Nisus Writer.”. United States Patent 5842203 . Search and read the full text of patents from around the world with Google Patents, and find prior art in our index of non-patent literature. Some of the Boolean operators which are primarily used in the patent searches are listed below. Initially, the Current Expression is the User Expression or CE=UE. Patent Trial & Appeal Board The NOT operator excludes unwanted terms from your Google sourcing search. In what follows, we shall use normal character combinations to make up Regular Expressions, leaving it to the implementation to use special symbols. 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. United States Patent and Trademark Office (USPTO) ... we recommend that you use our patent information search and analysis products, such as PATSTAT, Espacenet and Global Patent Index (GPI). 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. The words or symbols in bold represent the possible menu displays as well as the possible displayed expression custom symbol when entered into the find window. The list of Search Patterns is first scanned for any similarities. The symbols , , etc. Defines any character not in the user specified set. Conducting a patent search helps ensure your invention hasn't already been patented by someone else. This would limit the search results to only those documents containing the two keywords. However, fully constructed Boolean search strings can look both confusing and complex, and may seem difficult to write. touch OR screen

  –>  This search finds patents that contain either term. 60/105,722 filed Oct. 27, 1998. (xviii) URL Any set of characters that could be a URL (Universal Resource Locator on the Internet). 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. When the resulting ERE is passed to the ERE parser, that distinction is maintained by that parser. The Referenced Text is defined as that part (or all) of the Matched Text which matches the parenthesized part of the Search Pattern. In that way, users can easily program the search engine for automated taxonomy of text databases. Shorthand: −, (xxxii) 0 or 1 (shortest) This is the same occurrence designator as the previous one except that the match uses the shortest possible number of occurrence. (ii) Any Character or ¶. The USPTO is "unique among federal agencies because it operates solely on fees collected by its users, and not on taxpayer dollars". Most commonly, an inventor conducts a patent search to find out if someone has already patented their invention. Our patent search capabilities offer advanced boolean functions, structured search, biological search, classification search, filtering and sorting options to find the most relevant and important patents. 1. If CE contains no boolean operators, omit all steps of the pre-processor, passing CE directly to the Extended Regular Expression (ERE) engine. Type the inventor's name in correctly and select the years. 10. A combination of Boolean Expressions and Regular Expressions, together with the designation of the Search Target makes for a very powerful search engine. With the same Search Pattern, the Matched Text can be different on different finds. KELSAN TECHNOLOGIES CORP., CANADA, Free format text: A method of searching text data, in a computer system, including means for specifying a text pattern to be matched to said text data, within a search target said means comprising a language used to compose a search expression describing said text pattern, said language comprising regular expressions and a plurality of boolean operators, said method further comprising user means to specify said search expression, wherein said boolean operators are selected from a group consisting of AND and NOT and NEAR and FOLLOWED BY and NOT FOLLOWED BY and PERHAPS. , application filed by kelsan Technologies Corp of a list of search for.
