The Lens, started as Patent Lens 15 years ago, is open, free, no advertising (secure) and a public service. It searches in over 90+ jurisdictions and hosts 100M patent records. It is not just federated search, but comprehensive links, analysis, embedding and sharing of records, collections and annotations. It is run by a global social enterprise, Cambia ...

No. As mentioned in a comment, patents and patent publications are not the only sources of prior art. Professional technical journals, magazine articles, books and even youtube videos could contain relevant prior art. Also, CPC is a joint program of the U.S. and the EPO. Patent documents from other locations may not even have a CPC classification. To get a ...

DEPATISnet is the best option. It is a completely free database and belongs to German Patent Office. I have worked on the database for over three years and found that the result quality is as competitive as an expensive paid database like Thomson Innovation. Databases like Espacenet , Google Patents , etc. do not have proximity operators like "Word A and ...

In my corporate life I used paid services such as Micropatent and TotalPatent. Of the free patent search tools, I prefer The Lens over Google patents. The Lens provides more fine grained control and if you register (completely free) provides useful additional features such as saved searches, search history and collections. In addition, I find The Lens ...

What is this Formal Patent Search of Classification? I haven't been able to find any information on it online. Does it differ from a preliminary patent search (as explained on the CIPO website) in any meaningful way? A patent classification is a system to categorize (code) documents, such as published patent applications, according to the technical ...

There is an alphabetical index of USPC classes that you can use. For example, if you look up the word "mouse", you'll see that they are included in class 345. http://www.uspto.gov/web/patents/classification/uspcindex/indextouspc.htm

USPTO's PatFT provides functionality for this. In particular, the re-examination certificate (REEX, where REEX=YES refers to a certificate of re-examination being present) and current CPC classification class (CPCL) are probably be relevant. The query REEX/YES and CPCL/F25B seems to provide what you want.

You can either use keywords for filtering, or something better, use the patent classifications systems put in place by different patent offices. Based on the technical details of the invention, the patent examiners classify each patent application according to a hierarchical classification system; each examiner may assign one or more classification codes to ...

Not sure if this is what you are looking for, but the USPTO provides a classification structure that you can navigate through here ==> http://www.uspto.gov/web/patents/classification/selectnumwithtitle.htm

The existence of a patent does not necessitate the existence of a product. It is very common for patents to be written prior to any product development. The inventor may simply want to protect an idea prior to seeking investment for product development, or the product development may simply stall and never make it to market. In software patents especially, ...

Anyone can provide the services of a novelty/patentablity search or patent landscape report. However, a freedom to operate analysis is a different story. Even as a registered patent agent I am leery of freedom to operate. It is clear that only an attorney (does not need to be registered patent attorney) can provide a freedom to operate opinion. That is an ...

There are vast method to cover all patents filed by inventor, It depends on indexing of database, truncation or errors made while filing or indexing, language etc. A person has to design various keywords to cover all possibilities. Still researcher may not get complete information if patent office is not included in searchable database. To search inventor ...

in prior art search; you narrow down your search by using 'key words'. First one or two takes you to your field. Following Key words should represent your adopted means and methodology for solution to the problem you have chosen to solve.

This is an obvious error. The US 7,439,877 patent citation is the correct one because it is in the same space and has the same inventor as the patent in question. The two identifiers are only off by a single digit and have the same publication date: US7439877 May 18, 2007 Oct 21, 2008 Philip Onni Jarvinen Total impedance and complex dielectric ...

Performing a thorough patent search is a significant effort. Some people make a career of it. I think you should try to do it yourself first and then ask for help if you get stuck. Even though I don't consider myself a professional, here are some tips: First, it can be useful to do a basic Google search for such products. From this you can see which ...

Performing a patent search is something you can do for yourself for free. This answer describes my process. Searching with the terms "oversize golf grip" on The Lens resulted in 428 granted US patents dating back to 1977. Please understand that obtaining a patent takes time, typically three or more years. If you saw a product that looked like your idea less ...

It turns out that "www.google.com/patents" often has issues with displaying images and really shouldn't be used. If you really want to use Google then use the site "patents.google.com". Here is the same patent at patents.google.com. You'll notice that the images are displayed. Another option is The Lens. It is also completely free, but if you register, you ...

You might try Espacenet, The Lens or PatentScope - all are https

Google patents offers many ways to narrow a search. You might start with google patents advanced. It also has an "about" section. You can limit a search by country, status, just look in title, etc. Below is an excerpt from that information. Although google patents is usually used in a more simple way it does have Boolean capabilities and even now supports ...

As mentioned in a comment, patent applications are not published until 18 months after initial filing. If it is a U.S. only filing it is possible that non-publication was requested and no publication will occur until and unless a patent issues. If the authors are not all in the U.S. there is a greater likelihood of one or more applications filed somewhere ...

For the U.S. you can go to its patent search page and search for Legal Representative (LREP). I tried it with my first name last name, got 0 hits; first name middle initial last name, got 0 hits. Then I tried LREP/("George" AND "White") which would hit if anyone had my first name anywhere in their name AND also had my last name anywhere in their name. I got ...

There is no particular office I would say. Some patent offices have examiners more knowledgeable in some topics than others, then some examiners are better than others. You could file the same application twice with the same patent office and get two completely different search reports. Since no patent office guarantees a perfect search report, some ...

In the past I got several good searches with KPO as ISA. From the U.S. the cost is still about 1/2 what it would be from the EPO. When I started using Korea they were new and charged even less. It is not part of the body of the question but you could hire a search firm.

Yes - there are differences amoung these and others. The number of fields you can independently search with google patents is very limited and they are thought of as missing some recent documents. Unlike many others they do not have a way of setting up an account where you can save your work or any analytics. The Lens and others can give you charts of what ...

As an aside to George Whites excellent answer, if you know the patent or application number, Google Patents is generally the fastest way to the document. That said, I greatly prefer The Lens. When searching my own name on Google Patents, I have trouble getting all my patents listed. The Lens always reports them all. I think this has to do with Google Patents ...

Public Pair Searching by patent number 5269144 doesn't show you in there on the case data. There was a correction in 1999 but it is not listed with any documents on PAIR. Google uses data from the USPTO and in there you aren't listed as inventor on either the text or image data. These are the listed inventors: STANLEY P. MILLER NORTHVILLE, MI (US) ...

Any element (e.g. motion sensor, means of communication and of interface between functional parts) which is well known in the industry field and performs routine function does not add "some thing more" to claimed invention and will raise judicial exception (abstract idea) if such an element is found in claims. However, if a machine is 'novel' and 'non-...
