Exceptional Team, Rewarding Results.
After all these years, that’s what I value most: good judgment, open communication, and a team that’s genuinely committed to getting the search right.
GreyB has invested in AI and modern search technology, and that’s important. But what impressed me more was that they knew when technology could help and when experience and conversation mattered more. They didn’t force one approach. They used the right approach for the problem.
The team explained why they were searching in certain directions, walked me through the references they were finding, listened to my feedback, and adjusted the search as our discussions evolved. That gave me confidence that they were trying to find the best answer, not just deliver a report.
I’ve worked with a number of search providers over the years, and what stood out about GreyB was their willingness to stay engaged throughout the search. Other providers often treat those discussions as optional. I don’t. If I’m trusting somebody to do something as important as a prior art search, how can they possibly do their best work if they’re not talking to me while the work is happening?
I’m a retired patent litigator, and after spending decades in this profession, I’ve learned that good prior art searches don’t come from simply running more tools. They come from people who know how to think through the problem and are willing to work with the client.
Data is almost free now. What adds value is the judgment on top of the data. That’s the scarce thing.

That kind of insight only comes from really digging into the file wrappers and understanding what was missing. The motivation to combine was only identified by going into the file wrapper and finding the reference that fills exactly the gap the PTO said was missing.

I like the idea that you’re getting nuanced about implicit disclosures and inferences. Because if it’s expressed, it’s easy. It’s almost never fully expressed. That’s the hard part, and that’s where the value sits.

GreyB’s team brought a refreshingly interactive approach to our 5G wireless invalidation project. I wasn’t used to it, but it worked well. Arjun kept things organized and on track. Preetika, the technical lead, was well-prepared with highlighted passages during our interim discussions. That made it easy to follow, even with limited prep time. GreyB clearly showed how the invention evolved within the standards. It helped us see where the novel aspect came in and which companies were working on the tech. The results were well-explained, well-documented, and easy to follow from a legal perspective. Helped us quickly assess the strength

Arjun and his team delivered top-notch service on the invalidation search project. They kept us informed throughout the process and provided very useful interim reports with high quality technical discussions to achieve an excellent result. It was a seamless project from beginning to end.
1. The report and the additional helpful comments in your emails were easy to understand and read through. I did not need any extra clarifications. 2. I also appreciate the intermediate checks and sharing of the preliminary results from your end before the delivery of the final results – it was a good strategy to ensure that the search scope was targeting our exact need. 3. The search results in itself were found to be highly relevant and useful, and the feature mapping for the Amoako reference for all the targeted claims was well laid out. I particularly liked the

I’ve worked with GreyB for several years, mostly for patent invalidity searches, and recommend GreyB for high-quality, in-depth prior art searching. GreyB is very professional in their approach. Especially helpful is the way they share the updates on rolling basis and team’s ability to quickly adapt based on my feedback during these rolling updates. The teams assigned to specific projects are well-versed in the relevant technology. While they may not always find a perfect piece of prior art, their search strategies are robust and instill confidence that they have uncovered the strongest prior art that can reasonably be located.

I am very satisfied with the services provided by GreyB. The collaboration with the researchers was extremely efficient and pleasant. They quickly adapted to our feedback and found valuable prior art in both patent and non-patent literature. The final report was clear and precise, providing us with an excellent foundation for our next steps. The team’s expertise and flexibility exceeded our expectations.

I work on patent litigation matters in Europe and have been successfully doing this work in IP Industry for many years . I’ve been working with GreyB for a few years now, mostly on the invalidation side of things. I’d recommend GreyB to anyone needing an in-depth prior art search. What I appreciated most was the team’s ability to understand the subject matter of the claim very well. Overall, I am very satisfied with their work product & engagement process.

We were happy with the overall service. You were very eager and willing to meet deadlines. We very much appreciated that. You are also free to use that as a quote, or however you referred to it in your previous email. Sorry, for taking so long to get back to you, we have been working intimately with the results (I have also been sick). Thank you again Arjun, to you and your team, for you professionalism and timeliness.
