Patent Attorney Legal Services Used the software for: 6-12 months ### "ClaimMaster used as a QA tool for patent application drafts" June 2, 2021 4.0 ClaimMaster offers a wide variety of tools, but I personally use only a very small number of tests: Two tools for claim proofreading (checking for errors and checking for antecedent problems) and one tool specification proofreading (checking part numbers). Tried the other tools - they may have potential, but currently require too much work on my side to filter the results - as most issues identified by the other tools are non-issues (maybe these tools will be more efficient as technology advances, but not at the moment). Pros Good tool for capturing typos and errors in claims, check for antecedent problems, and going over part numbers throughout the spec and the drawings. Cons Still requires manually reviewing all reported issues as most are "false negatives", especially when checking for antecedent problems (many terms may be a bit confusing, and automated tools don't always capture these correctly). Has some difficulties with proper interpretation of part numbers that appear in drawings with superscripts or subscripts. Review Source DB Dave B. Attorney Law Practice Used the software for: 2+ years ### "Great Tool for Patent Preparation & Prosecution" April 9, 2024 4.0 Pros It's a feature-rich product, so there will be some features that are real game changers even if you don't use everything on the menu. It's great for checking claims, drawings, numbering, etc. Cons Some features are a little buggy, but the ClaimMaster team seems to be constantly improving the product over time. Reason for choosing ClaimMaster Lower cost, didn't need the added features in the other product. Review Source dM david M. Patent Attorney Legal Services Used the software for: 6-12 months ### "Great Help For Patent Attorneys" May 19, 2021 4.0 Good, it has been helpful in ensuring I produce high quality patent applications Pros That it has autocomplete features with terms used in claims or on part names. I also like the antecedant basis checking features. Cons That it is a subscription payment model and not a one-time payment model. Also, the tool seems to take too long to gather the information on terms, claims, etc. and seems to constantly re-parse the document and/or claims before I can use features. I understand that re-parsing is necessary to some extent, but the tool seems to be excessive with this. Reason for choosing ClaimMaster I think Turbo patent is too expensive for my needs. Review Source DM David M. Patent Attorney Legal Services Used the software for: 2+ years ### "Helpful Tool" May 17, 2021 4.0 On the whole, ClaimMaster has been a great time-saver for us, and it's helped us eliminate errors in our work. Pros ClaimMaster has been very useful for our firm as a tool for drafting and reviewing patent applications, automating IDS generation, and generating patent family trees. It can speed up patent drafting considerably, especially if I put together a parts list in advance, and use the "//#" notation to automatically insert part numbers. ClaimMaster almost always finds antecedent basis and/or reference number problems in draft applications; it helps us fix these before client review and filing. Cons I do wish the parsing features worked a little more rapidly, or more in the background - I can't use Word while they operate. I also get several false positives from antecedent basis and drawing reference number checks. These are easy to ignore, but would be great to resolve or customize. Review Source LC Laura C. Paralegal Legal Services Used the software for: 2+ years ### "Love the IDS Generator" May 17, 2021 4.0 Time is of the essence and accuracy in my field. ClaimMaster assists me with being more efficient and accurate. Thank you ClaimMaster! Pros I mostly use the IDS Generator to assist in preparing all of my IDS. It saves me a lot of time, and functions relatively well with only the occasional glitch. I was able to integrate the software into my current business processes effortlessly! Cons Occasionally the published dates get off and then throw off all subsequent reference dates. Not a big deal compared to the amount of overall time ClaimMaster saves me. Review Source CR Charles R. Managing Member Legal Services Used the software for: 2+ years ### "Amazing" May 17, 2021 5.0 Saving time doing repetitive tasks. Pros Antecedent checking for claims. This is terrific. After you have checked your claims, the software can then enumerate every place in the specification where support can be found. Likewise, it can check part numbers and verify them versus the drawings. This is especially good for finding slight, unintended shifts in terminology. Finally, the software does a great job of manipulating claimsets during prosecution. Cons I recognize that the software is trying to help with some very hard conceptual processes and the ability to prepare responses ready for the lawyer looks like it could be helpful. But since it is so complicated, I think they need a white paper explaining not only how to use it, but the concept they had in mind when they designed it. This would augment the instructions. Review Source DP Dallin P. Associate Consumer Electronics Used the software for: 2+ years ### "Extra Eyes!" April 9, 2024 5.0 Pros ClaimMaster is great at finding nuanced antecedent issues, as well as identifying figure number discrepancies in specifications. Cons It does not catch as many antecedent basis issues as I would like. Review Source PS Paul S. Patent attorney Law Practice Used the software for: 2+ years ### "Time saver and accuracy improver" May 17, 2021 5.0 Pros Claimmaster is great at detecting errors that are time consuming and difficult to detect manually. Using it to confirm dependencies, consistent reference number usage, antecedent basis, claim numbering, and the like is a great time saver. Cons There can be a large number of false errors. But sorting through these usually turns up other minor issues that are best corrected before filing anyway. Review Source HH Howard H. Patent Attorney Legal Services Used the software for: 2+ years ### "Key tools for offline review" June 1, 2021 5.0 Patent application quality is improved by adding machine-based revision in addition to manual proofreading. Pros ClaimMaster provides key application and claim review functionality for patent and office action drafting. The time saving utilities (claim renumbering, status indicator updating, etc.) are also very helpful. The ability to work offline is key in some instances. Cons Windows only. No native Mac OS version. Review Source SB Sara B. Patent Attorney Law Practice Used the software for: 2+ years ### "Really helpful tool" June 1, 2021 4.0 Overall, this is a really great tool for the money. It handles a lot of issues that are otherwise time consuming to identify. It makes the final product just a little more polished and professional, which is really important. Pros The ease at which I can quickly review for errors that are difficult to find it really wonderful. I can quickly ensure part numbers are correct in my spec, and there aren't claim issues. I also like the other tools like quickly generating a shell for my responses. Cons I wish it would automatically update the information panel as you resolve issues. The features that allow you to click around and find errors do not work well as you resolve the issues and continue clicking around. I find I have to run the tool several times to ensure I've found everything. Review Source MK Malgorzata K. Partner Law Practice Used the software for: 2+ years ### "ClaimMaster Review" June 1, 2021 5.0 Excellent! Pros Automation. With just a couple of clicks, one can receive a comprehensive summary of all errors in the claims and of all errors in the patent applications. Cons Occasional ambiguity in parsing the claims.

Partner Law Practice Used the software for: 2+ years ### "PCM is essential for patent prosecution" June 8, 2021 5.0 My experience has always been amazing, which is why I have always renewed for about 8+ years now, as I recall. The customer service from Dmitri is especially good. Pros This software has many features, but the most important ones are checking for antecedent basis, numbering, and formatting errors in claims. It catches things that most human eyes easily miss, and it cuts down on review and proofreading time dramatically. It pays for itself easily. Cons I have no complaints. This software works incredibly well. Review Source JB Jeremy B. Managing Member Law Practice Used the software for: 1-2 years ### "Outstanding value for boots-on-the-ground patent prep and pros " June 1, 2021 5.0 I've used this product for several years now, just about every day. It is a fantastic tool that I'm not willing to be without. Pros Part number review and claim antecedent review are top notch. Cons I don't perceive any weaknesses- complete value Review Source DM Devin M. CEO of Miller IP Law Law Practice Used the software for: 2+ years ### "Great tool to avoid drafting erros" May 17, 2021 5.0 Pros We use this tool on each patent application we draft to ensure quality. Works great. Cons Has a ton of great features, but sometimes it is hard to navigate between the features. Review Source TM Todd M. Patent attorney Law Practice Used the software for: 6-12 months ### "Great product a "must have" for patents" May 18, 2021 5.0 This software is a necessity for modern patent drafting. Pros Checking reference numbers and claim terms in spec. Cons I probably need some training on customization. I'm usually too busy to look into that. I like the flags on the claims because it let's me think about an issue. Review Source Jose N. Patent attorney Law Practice Used the software for: 2+ years ### "Great tool for claim checking and using LLM to describe figures" April 17, 2024 5.0 A perfect ten. It's a useful tool and I like to have it handy while I work on Microsoft Word. Pros I like that the tool is installed on my PC and is compatible with MS Word, so I don't have to log in all the time and worry about being spied on my activities. I've used CM for more than ten years, and my favorite feature is checking that the claims are correct. I also like the claim summary for responses to Office Action. Cons Nothing in particular that I like least about CM Review Source TF Theodore F. Patent Attorney Law Practice Used the software for: 2+ years ### "ClaimMaster Review" May 18, 2021 4.0 Overall, my experience is positive. Claim Master is an important part of my quality assurance process. I will continue to use Claim Master. Pros ClaimMaster does a good job at finding antecedent basis issues in the claims and the specification. I rely on ClaimMaster almost every day to make sure that my claims do not have 112(b) problems that can arise from missing antecedent basis issues. ClaimMaster is an important part of my patent preparation and prosecution practice. I do not believe a work product is complete unless I've checked it with ClaimMaster. Cons ClaimMaster is sometimes wrong. Fortunately, it tends to have a lot more false positives than false negatives. (False positive = flags an antecedent basis issue, but it's not; false negative = fails to flag an antecedent basis issue that does exist.) False negatives are quite rare, but they can pop up when the claim terms get complex. False negatives often happen when an adjective is used in front of a claim term (particularly in the specification), or when the claim term gets particularly complex (e.g., more than 2-3 words long). However, I would rather that Claim Master overflag possible issues and let me double check and resolve them. If I had to choose, I would much rather deal with false positives than false negatives. It can sometimes take a while to work, particularly if I have a long application and I ask it to do a full check of the specification and figures. During this time I can't switch windows within Word to work on something else, and that is a bit frustrating. Reason for choosing ClaimMaster N/A Review Source Jack A. Attorney Law Practice Used the software for: 2+ years ### "Great productivity software for patent attorneys" April 9, 2024 5.0 Great value. They keep the product updated with the machinations of the USPTO patentcenter site. Pros The value proposition is strong as this product does a great many functions. From IDS generation to claim proofing, it does it all. Cons The user interface can be a bit complicated at times. Review Source SC Sam C. Managing Partner Law Practice Used the software for: 2+ years ### "An indispensable tool" June 4, 2021 5.0 As noted, this is an indispensable tool in preparing applications and responses for us. There is little more I can add to that (or need to, honestly). Pros Installation of this product is effortless. The product works quite well and is easy to use. Constantly being improved. Customer service is second-to-none - I wish all our IT projects were as well-supported and effective. I use this product constantly, and find that I can prepare applications and claims in a MUCH more efficient and affective manner when my process includes ClaimMaster. Further, not having to allow remote access to any of our documents is an absolute necessity. Its standalone nature is critical, as we have clients that forbid the use of any software that employs remote access and/or sending files over the Internet. Cons The only complaint I can think of is that certain phrasings confuse the software. It may be possible to use natural language processing/machine learning to address this shortcoming, but again, it would need to be implemented as a standalone system, for our purposes. Review Source DV DAVID V. Partner Law Practice Used the software for: 2+ years ### "Essential Tool for Patent Prosecutor" June 2, 2021 5.0 Overall Claimmaster has provided itself to be an important tool for patent prosecution, especially claim review and IDS prepartion. There are many other helpful features. Pros The product makes claim review and updating in amendments and the original application a much easier task. The product does a great job of catching antecedent basis and claim numbering type of mistakes to supplement the practitioner review. The IDS tool to fill out IDSs with the patent publications has been a big time saver for staff. There are numerous other helpful features, such as checking the specification for reference number consistency. Cons Would be helpful to be able to add non-patent literatore to the IDS as part of the auto-fill feature. Would be great if there would be a way to manage cross referencing references in IDSs between related cases and autofill IDSs when references are added to one case. Review Source DS David S. VP, Research and Development Automotive Used the software for: 2+ years ### "Powerful, easy to use software" April 9, 2024 4.0 Very good experience, for the cost and performance it is great. And I can’t stress enough how good customer support is! Pros Automation of tasks, connecting and graphing patent families, amazing customer support Cons Petty maybe, but having to click on an empty field for entry instead of having the software accept typing automatically. Review Source SZ Steve Z. Patent Attorney Law Practice Used the software for: 2+ years ### "An essential tool for practicing patent attorneys" June 1, 2021 5.0 I have used ClaimMaster since it was first introduced. My experience has consistently been good, to the point where I would literally not want to write a patent without it. Pros ClaimMaster has many functions, but the part I like most is claim analysis. Claims are arguably the most important part of a patent. However, to be valid, the claims must follow many legal and logical rules - so much so that they are almost like short chunks of high-level computer code. As a result, it is all too easy to accidentally introduce errors. ClaimMaster quickly and easily scans claims and detects and highlights many of the most common patent claim construction errors. I find it to be an essential tool for my practice. Cons I have generally found the software to be easy to use, and have no complaints. Review Source JH James H. Patent Attorney Legal Services Used the software for: 1-2 years ### "Great Product and Great Pricing" April 9, 2024 5.0 Pros The features are difficult to match in other products costing twice as much. It works well, and they add new features to keep it competitive. Cons I don't really have any cons, although I look forward to more AI functionality cover time. Review Source RK Richard K. Partner Legal Services Used the software for: 1-2 years ### "You're crazy if you don't use a bot like claimmaster" April 9, 2024 5.0 It's been a major factor in improving the quality of my USPTO submissions. Pros It catches stuff. Running claim sets and application drafts through claimmaster is one of my essential quality checks. Cons Defining patent terms can be difficult and often fails. Sometimes I want a string (including spaces) to absolutely be interpreted as a claimed element for antecedent basis checks. I enter it into claimmaster and, if I'm lucky, it works. Review Source RS Richard S. Owner Legal Services Used the software for: 2+ years ### "Fantastic Patent Prosecution Assistant" April 9, 2024 5.0 I've been a user of ClaimMaster since it initially came on the market. When I was at a large firm, I convinced it to buy multiple licenses and would insist that associates run reports through ClaimMaster before bringing me something to review. Pros The ability to begin preparation of Office Action responses and the diagnostic tools for reviewing documents for errors Cons Not much, really. Some parts of it I don't use because I already have good tools. Review Source
