This, and all similar succeeding symbols, when used, require the user to enter the respective numbers into a dialog. Good examples of such use of special custom symbols are the, already mentioned implementations of the PowerFind feature in Nisus Writer and in PowerSleuth. The NOT operator excludes unwanted terms from your Google sourcing search. Some of the Boolean operators which are primarily used in the patent searches are listed below. A few techniques consistently resonate with our clients and almost always generate the proverbial “Ah ha!” moment. Simulating the NOT operator is not possible without additional features. Logical expressions, on the other hand, can only be concatenated using one of the binary boolean operators. Quite often, particularly for automated taxonomy applications described below, it is useful to be able to search for any one of a long list of Search Patterns. :(A:. Newly Added Patents. A single light source is divided into a matrix of light beams using b ... United States Patent 5251052 ...

But never fear! We make every effort to prevent errors and discrepancies in the … The following table is used in the replacement of booleans with GREP expressions. Shorthand: \v, (xxiii) Space The literal typed space. ‘OR’ – The OR operator is used to search … Shorthand: :(, (xlii) } The right closing NR Parenthesis. User designation of the target is particularly needed in the use of NEAR. As users of the search engines become more discriminating and more experienced, they will demand more control than even the current advanced search engines can provide. Some veteran patent searchers I know may spend a day or more refining and testing a query, but once it is done, they can save it and reapply it over and over. The subsequent “\1” refers to this Referenced Text, and means that the same text is repeated in the next paragraph. Shorthand: [ ], (xvi) User Negative Set [{circumflex over ( )}] Enters the brackets with the caret and the insertion point between them, allowing the user to enter either a range of characters or an enumerated set. Weiterführende Informationen geben Aufschluss darüber, ob ein Patent erteilt wurde und ob es noch in Kraft ist. A method of searching text data in a computer system, the method comprising: a) constructing a plurality of regular expression (RE) terms, each RE term using a plurality of different nonliteral RE symbols to describe a class of text patterns; b) modifying the plurality of RE terms by a plurality of different Boolean operators to form a Boolean RE search pattern; and. This search engine allows you to search the USPTO's database of registered trademarks and prior pending applications to find marks that may prevent registration due to a likelihood of confusion refusal. 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. Reference Parentheses are parentheses whose purpose is that of grouping of Search Patterns, of defining or clarifying the precedence of their evaluation, and of creating a … Fees and payment. 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. The following is an explanation of how a suitable search pattern is made up. It would, therefore, definitely be worth reaching out and “pitching” such sites. Contact Us. If at any time the sum is negative, stop the scan and return an error of unmatched parentheses. Most commonly, an inventor conducts a patent search to find out if someone has already patented their invention. Boolean operators are the soul of a patent search. Imagine being able to find at least 20 perfect candidates in under half an hour!. Patent Buddy offers a free search of patents, inventors and current patent owners. However, frequently we need to search for a text string which can be intuitively designated as. Construct your query containing 20 or more terms, and OR them together. Shorthand: {,n}, (xxxv) From m Times Means the preceding character, wild card or parenthesized expression is to occur “m” or more times and assures the longest possible match. Patent legal status. PatFT: Patents Full-Text from 1976 Quick Search Advanced Search Number Search View Full-Page Images PatFT Help Files PatFT Status, History PatFT Database Contents Report Problems << BOTH SYSTEMS >> The databases are operating normally. Keep in mind, weighting a term will not affect the search engine’s recall. For example: which means that Software is to succeed (anywhere within the target) the word Nisus. Certainly, you’ll iterate and refine your OR’ed searches too. Mar 20, 2017 - US Patent Full-Text Database Boolean Search. NOT always excludes documents with the specified term. The definition of a word includes a sequence of alphanumeric characters, excluding any characters which are word separators. In other words, it is a very liberal text pattern definition of a phone number but it would hardly ever match any text which was not a phone number. This is typically not too difficult. This would limit the search results to only those documents containing the two keywords. Does not begin a reference. Make your best intelligent guess at a well-constructed query and run it. Erste Schritte; … A simple sum-of-bytes hash function would work. For example, a Boolean search could be "Apple" AND "bluetooth". 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. Each expression is a string of symbols and the plus sign designates string concatenation. Global Dossier provides access to the file wrapper of a patent application, wherever it is made available by the patent authority in question. The USPTO is "unique among federal agencies because it operates solely on fees collected by its users, and not on taxpayer dollars". This includes any character and includes the Return or new paragraph character. This database lets you access 152 years of patent descriptions and images.

The symbols , , etc. For example, using uppercase to designate operators and lowercase to designate any boolean expression, the boolean expression, cannot generally be concatenated with the boolean expression. Canadian Patents Database / Basic Search Bilingual searches are now possible . Conceivably, you could even do this type of search in a language that you don’t even speak or a technology with which you have no familiarity and still get highly accurate results. In other words, if you weight “touch” higher than “polarize” you’ll get the exact same number of results, but it will change the sort order and favor patents with the terms you’ve weighted higher. You’ve probably heard of the saying, “you only get out of it, what you put into … For example, a boolean expression such as (A AND B) concatenated with (C AND D) will give an error in the Boolean interpreter, whereas its intuitive meaning as a GREP expression would be: Although a new design for a unified parser and search engine can be easily developed to better implement the invention, an alternative method of implementing it is described here, which provides the same result through a simple pre-processor, allowing existing code bases for the GREP and Boolean interpreters to be used. In applications, each of these symbols can be made a distinctive symbol so as not to be confused by the user from any similar characters which are meant to be search literally. 12. Sometimes, what may seem like a basic concept, can trip up even the most experienced search specialist who may not realize how the search engine is really working under the hood. f) providing, for the step of constructing a plurality of RE terms, a plurality of symbols interpretable to represent a substantially complete set of nonliteral RE operators; and. Shorthand: [{circumflex over ( )}]. 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. 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.

Use the Boolean OR, particularly with a large set of terms that are likely found, but not necessarily found in every relevant document. Classification search in Espacenet helps you to find suitable classification symbols for your search, and then to apply in the search itself. The extended Regular Expressions, a part of the current invention, allow for a Search Pattern description that is as specific or as broad as the user wishes. The operator NOT on its own is a Unary Operator and negates the presence of the Search Pattern that follows it. N R Parentheses (Non-Referencing Parentheses) are those which do not create a reference to the matched text but have the other functionalities of parentheses, i.e. Biologicals. ii) accepting a specification of the search target that is less than an entire text document. Aug 2, 2005 Grant Date; N/A app pub date; Jul 5, 2000 filing date; Jul 5, 2000. priority date . Pick the top N terms that you discover occurring in the documents with a reasonable frequency, where N is usually between 20 and 30 terms or strings. Such changes would make it possible for continual and easy refinement of the pattern matching expressions. FIG. touch AND screen
  –>  This search finds patents containing both terms. 2 is an example Karnaugh map based on the diagram shown in FIG. Delisted Patents . Boolean search is a type of search allowing users to combine keywords with operators (or modifiers) such as AND, NOT and OR to further produce more relevant results. Clearly the chances that a document, containing the specified words, is the one we want is lower if these words are spread throughout a long document, rather than if they are all within one sentence, or one paragraph. For the latest updates of the database, see the Currency of information page Saved by … Abstract: In the field of computer text search engines, regular expression text pattern matching is combined with an extended set of Boolean operators. }:) The second alternative speed-up process would use a simple hashing function to reduce each of the listed words to say a 16 bit number. Conducting a patent search helps ensure your invention hasn't already been patented by someone else. Shorthand: :−, (xxxiii) n Times Means the preceding character, wild card or parenthesized expression is to be occurs exactly “n” times. Search one site (like wikipedia.org) or limit your results to a domain like .edu, .org or .gov. You probably learned it the first time in 6th grade.

Doe, … Extended GREP (output) Google patent search also offers the option to search keywords that are not directly next to each other but fall within close proximity. A reconfigurable digital optical lookup table for solving Boolean equations sing an array of bistable optical devices is provided. Shorthand: Å, (viii) Any Text, Short. This process, which leverages the Boolean OR and the relevancy-sorting algorithm, is repeatable for any technology. The backslash before the period is needed because in this context the period is meant literally, whereas in the list of Shorthand symbols it means “Any Character.” The minus following the period means that it too need not be there. For example it would also find the text: “programming searching algorithms.” Although this is not one of the stipulated Search Patterns, it certainly makes sense to have it be part of the list. These patent applications are assigned classifying symbols or codes that make it easier to search for other patents. When boolean operators are included in a Search Pattern, the result is a Boolean Search Pattern.

AND always narrows your search. Shorthand: . For example, suppose the Search Pattern is defined by: where each “:w” stands for any character which can be part of a word, and “\<” stands for the beginning of a word, and “\>” for the end of a word (each of which is not a character just a position) then the example text pattern represents any four letter word. With this addition, the GREP Search Engine is referred to as the Extended GREP Engine and the expressions it can process are referred to as the Extended Regular Expressions. Patent Board, consisting of Secretary of State, Secretary of War, and Attorney General, established by the Patent Act of 1790 (1 … 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. Defines any character in the user defined set. In my role as a partner at AcclaimIP.com, 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. Start typing in the box with the cursor. Patents. Just remember, that’s why we patent searchers get paid the big bucks .

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. Owners (US) Document Types. (Usually NEAR means within 10 words of each other, and this number of words is not under users control.). 3A-3B are diagrams of an example Boolean space expressed as a torus. 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). The Referenced Text is defined as that part (or all) of the Matched Text which matches the parenthesized part of the Search Pattern. Another example of the Search Pattern is a Regular Expression (RE) Search Pattern. Grep expressions can be concatenated to form new meaningful expressions whose match is the concatenation of the respective matches—an intuitive result. Create collections, alerts … The Search Target, is that sub-text element which is to be searched through for an instance of the Search Pattern. File a patent application online with EFS-web.

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. If CE contains no boolean operators, omit all steps of the pre-processor, passing CE directly to the Extended Regular Expression (ERE) engine. 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). ASSIGNMENT OF ASSIGNORS INTEREST (SEE DOCUMENT FOR DETAILS). touch NOT screen

  –>  This search finds patents that contain the term touch but not screen. Shorthand: (, (xl) ) The right closing Reference Creating parenthesis. Search firms are often listed in the yellow page section of telephone directories under the heading "Trademark Search Services" or "Patent and Trademark Search Services." For example, if the Search Target is a sentence, and the Search Pattern, is: any sentence which contains both the word “Nisus” and the word “Software” without regard to the order of occurrence, would be found as a match. RE Search Pattern is a Search Pattern which does not contain any boolean operators other than the Or. Our improvement will help those of you who know your search criteria in one of Canada's official … The following steps identify the operator (Op) and operands (A,B). e) employing a set of Boolean operators including operators substantially similar to AND, OR, NOT, NEAR, FOLLOWED BY and NOT FOLLOWED BY, such that each of the operators is used in at least one of the plurality of Boolean RE search patterns. This would limit the search results to only those documents containing the two keywords. Copy and paste each one as-is, or edit to fit your search needs..Net Developer.Net AND (VS OR “Visual Studio”) AND (VB OR “Visual Basic” OR VB.net) AND (ASP OR ASP.net) AND (C# OR C#.net ) AND “SQL Server” Android Developer :*B:) To narrow your search to hits occurring within a single field, precede your search term with the field code, followed by a forward slash (/). In what follows, whenever we need to use literally a symbol or symbols which also have a Shorthand special meaning, we preceded it with the backslash “\” If the special meaning combination includes a backslash and we want to designate the backslash literally, we use two backslashes. For example, if we were making up a list that would find articles on searching algorithms for programming search engines a possible partial set of three of the patterns in such a list would be the following: These could be combined into the following single Search Pattern, to which we shall refer as the “Hybrid Pattern:”, (programming)−\s+search(ing)−\s+(engines-)−\salgorithms−. :*B Or B:. Here is how: All modern patent search engines have sophisticated relevancy algorithms under the hood. First is the ability to combine similar patterns. For example, if you are searching for power control methods in CDMA mobiles, finding the exact order of keywords may not be possible. Patents from 1790 through 1975 are searchable only by Issue Date, Patent Number, and Current US Classification. People might use different words to say the same thing. The expression “Or” is the GREP disjunctive. Boolean Search Pattern is one which contains one or more Boolean Operators. In the field of computer text search engines, regular expression text pattern matching is combined with an extended set of Boolean operators. … Sign up Today! Classification Explorer. To use such a notation, we need a menu means to select from, and a display means that distinguishes each symbolic expression from plain text. Such an expression, for example, can be used to find repeated words or phrases in an alphabetized list of such words of phrases. We have added a feature to help you to conduct searches simultaneously in English and French. 60/105,722 filed Oct. 27, 1998. Reference Parentheses are parentheses whose purpose is that of grouping of Search Patterns, of defining or clarifying the precedence of their evaluation, and of creating a reference to that text which matches the parenthesized Search Pattern. Shorthand: *, (xxviii)0+ (shortest) This is the same occurrence designator as the previous one except that the match uses the shortest possible number of occurrences. Your search engine likely has keyword analyzer tools. Once named, the name of the list would identify it in the Find window. When searching for any one of a number of Search Patterns defined by such a list, it is possible to optimize the search engine in the following way. When the resulting ERE is passed to the ERE parser, that distinction is maintained by that parser. 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. The combinations AND NOT, and NOT FOLLOWED BY are also Binary. The invention is unique in that it combines both the full Boolean search and the Extended GREP search. If we wanted to designate \s literally we would write \\s. For example, the asterisk is not supported on LinkedIn. The common syntax errors are the following: (a) Unmatched parentheses. The present invention combines the features of the full boolean search with the extended Regular Expression search features, adding the control of the search target, to create a more powerful and useful search engine than any presently available. 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. Shorthand: ¶, (vii) Any Text. and means that the search is to find an instance of the word “Nisus” not immediately followed by the word “Software”. You can create files that you can export, which makes it easy to compile your search results. (d) If any two Binary operators follow each other with no intervening expression, report an error. Try the beta replacement for EFS-Web, Private PAIR and Public PAIR. The following step-by-step process describes the construction of the Pre-Processor. Boolean Search Operators can be used on just about any search engine. Welcome to CIPO's Canadian Patent Database.
