Slide 3 Definition of Patent A patent is a legal title granting its holder the exclusive right to make use of an invention for a limited area and time. Before 1995, utility patents are in force from 17 years from the date of issue. From 1995 to present, utility patents are in force for 20 years from the date of application. Design patents are in force for 14 years from the date of issue. Plant patents are in force over the same period as utility patents. The rights given by a patent stops others from, amongst other things, making, using or selling it without authorization Also note that patents can not be renewed. (Figa, 1998) Slide 4 Three types of patents Design (has to do with the appearance of an item): Ornamental design for an article of manufacture Plant (agriculture): Distinct and new variety of plant Utility: (this is the type most often associated with invention) Process Machine Article of manufacture Composition (Gordon & Cookfair, 1995, p.16) Slide 5 Utility patents classes Process one or more steps performed on a material, composition, data or article to produce a change in its characteristics. method of making chemicals fabricating metal parts data manipulation Machine group of elements or parts that interacts for a result dishwasher carburetor lathe Article of manufacture -- practically anything made by humans toothbrush table golf ball Composition of matter -- chemical compound or mixture of ingredients toothpaste cleaning solution Slide 6 What Qualifies a utility patent? Novelty. It must be the first of its kind. Usefulness. It must be useful. Not Obvious. It must not be obvious to others of ordinary skill in the field to which the patent pertains.

(Carr, 1995, p. 3) Slide 9 Why Patents? Patents may be the only source of technical information from a corporation regarding their research. (C. Wenger, personal communication, March 2000) Slide 10 Patent Sources of Importance to OSU: USPTO Espacenet Slide 11 Searching by patent attributes By subject assume most common Patent title, number Inventor Date of invention Country of origin Slide 12 Constructing a keyword search: generate & list terms What is known about the invention? Function Describe what it does in as many ways as possible; use synonyms Structure What parts compose it? Electrical? Structural and chemical forms: steel, silicon,etc Chemical reactions? What are end products? Slide 13 Expand on terms Boolean logic Computer Literature Searching Worksheet Slide 14 Boolean Logic {IDEA A(1) TERM(S)} OR {IDEA A(2) TERM(S)} OR Retrieves all records including either term. -- usually used to connect synonyms in a search Example: column OR pillar {IDEA A TERM(S)} AND {IDEA B TERM(S)} AND Retrieves only those records containing both terms. -- usually used for contrasting terms in a search Example: brittle AND elastic {IDEA A TERM(S)} NOT {IDEA B TERM(S)} NOT Excludes records containing a particular term. Example: brittle NOT elastic CD-ROM WORKSHOP; u.wisconsin, madison; njb, mmc, pjh 12/89 rev. for IIT, cbw 2/99 A 1 OR A 2 A AND B A NOT B Slide 15 Computer literature searching Idea 1 Idea 2 Idea 3 (Synonyms or Alternative words) (Synonyms or Alternative words) (Synonyms or Alternative words) -------------------------------------- ------------------------------------- --------------------------------------- OR OR OR -------------------------------------- ------------------------------------- --------------------------------------- OR OR OR -------------------------------------- ------------------------------------- --------------------------------------- OR OR OR -------------------------------------- ------------------------------------- ---------------------------------------- AND AND STATE YOUR TOPIC IN A SENTENCE OR PHRASE Sample: brake lights with varying intensity UNDERLINE THE 2 OR 3 MOST IMPORTANT IDEAS Write each of these ideas on the first line of a different column above.

(1790 to the present for class/subclass searching.) Select advanced searching Search by field codes also. Slide 19 Espacenet 1. Espacenet multiple country, weekly update 1. worldwide 30 million documents 1. Searches title and abstracts, get all WIPO, EP, US and JP. 2. Quick search: simple text (default search) 1. Searches title and abstracts, etc. 2. Notes field shows WIPO, EP, US, JP which means 117+ countries 3. Advanced search more options, with examples provided. Slide 20 Espacenet Advanced search Keyword search title or (title and abstract) Search International Patent Classification (recommended for a more comprehensive preliminary search). Slide 21 US Patents: 18 Month rule 18 month rule for publications of US patent applications took effect in 2001. With that rule, published applications of US Patents appear after 18 months from the date they are submitted to the Patent Office. Applications of US Patents appear in Published Applications file on the USPTO website After the patent is made official it appears in the Issued Patents file on the USPTO website. Slide 22 EP & WIPO US patents applications filed with EP or WIPO (subset of all US patent applications) appear in Esp@cenet after 18 months has elapsed.Esp@cenet EP European Patent Office WIPO World Intellectual Property Network Slide 23 Steps involved in a preliminary patent search 1. In USPTO: Search Issued Patents using keyword; Rough search, hit or miss Useful - Find a relevant patent Only works for patents from 1975 to present Thorough search requires searching class, subclass, which goes back prior to 1975. Slide 24 preliminary patent search cont. 2. Identify relevant patents and the corresponding class/subclass codes (CCL) 3. Search Issued Patents with all CCL identified using Tools..searching by Patent Classification or Advanced Searching link on the USPTO search page (be sure to select all years 1790 to present). And look at every single patent. Slide 25 preliminary patent search cont. 4. Search Published Applications using all CCL identified. Look at all patents listed. 5. Search European, WIPO, and Japanese patents via Esp@cenet, including international class codes search.Esp@cenet Slide 26 USPTO http://www.uspto.govhttp://www.uspto.gov US Patents 1976 to the present Select advanced searching Select 1976-present on the pull down menu - default Slide 27 Search What terms would one use to locate patents on friction testing devices, pertaining to friction between moving parts, and friction and lubrication issues, etc. Slide 28 Search Issued Patents friction and testing searches full text -- 20,000 patents Search within the abstract to eliminate irrelevant patents abst/friction test -- searches the abstract 8 patents -- cannot use truncation $ within a phrase abst/friction and abst/test$ -- searches the abstract 278 patents search limited to abstract with Boolean operator gives more results Slide 29 Slide 30 Slide 31 Item 49 Slide 32 Slide 33 3 class/subclass codes Slide 34 Select ToolsSearching..Patent Classification Link Slide 35 Enter the class number, 73 Slide 36 Then scroll to the subclass, 9 in this case. Slide 37 Click on P to the left of 9 for patents, or select 9 for the definition of the subclass Slide 38 Look at each patent to see if it matches your topic. Then search class/subclasses 73/7 and 73/121 and look at each patent in the results to see if any of them match your topic. At any given time during your search, you may discover other relevant patents and class/subclasses. The goal is to identify all class/subclasses (CCL) that pertain to your topic, then review the corresponding patents. Slide 39 Definition for 73/9 Slide 40 Searching class/subclass using advanced search and selecting 1790-present produces the same result Select range 1790 to present Slide 41 Search other relevant class/subclasses already identified before proceeding to search the published applications Slide 42 Search Published Applications using all CCL identified in the search of issued patents Slide 43 Slide 44 Look at each patent listed for this class/subclass & other relevant class/subclasses, including ccl/73/7 and 73/121.
