    _

    Thanks for all the handholding and advice. We truly appreciate the advice from your good self and the efforts of all concerned from your Office.

    I would like to thank you and your team for your continuous support and appreciate you all for being a part of TCS’ IP growth journey.

    Dear Mohan and Niti.
    I hope that you and your family are well. Thank you for handling this matter and the subsequent discussions with the controller, which led to a patentgrant. It is greatly appreciated.

    Thanks a lot RKD team for guiding us through the process. Special thanks to Dr. Dewan who had been instrumental in initiating this process.

    They are outstanding! The speed of their work is phenomenal. They are very practical and straightforward. It’s a fantastic firm and I am very demanding in my expectations.

    I am 100% satisfied, which is very rare. They bring both, professional relationship and a personal one. They have a different touch that makes them a shade better then the rest. They function on time and I never have to remind them.

    The “impeccable” Dr. Mohan Dewan is Head of IP litigation and principal of the firm. He handles patent and trade mark cases in both civil and criminal courts. Sources extol the dept of his expertise. According to one “ Mohan does seem to know everything, even about very niche technologies, which we find very impressive.

    Thanks once again for the kind, painstaking and swift efforts of Dr. Dewan and his dedicated team for truly making my dream come true!

    They keep us up-to-date and always deliver prior to the deadlines. Distance and time differences is not an issue with them.

    Smeeta was very efficient and the trade mark application has now been filed. A copy of the correspondence is attached. My client is pleased with the service and so I am.
