PATENTS RELATED TO STREPTOMYCES

Although Dr. Demchick also represents patent seekers with non-microbiological inventions, his doctorate is in microbiology. Microbiology has been the primary focus of his research and teaching. He especially loves dealing with patent searches and applications for involving microbiology.

Dr. Demchick is a scientist with a quarter of a century of research experience in academic, industrial and governmental settings.

If you are considering patent protection for an invention, Dr. Demchick will be glad to discuss the matter with you. There is no charge for an initial discussion.

The following sampling is to give you some sense of the types of streptomyces related inventions which have received United States patent protection. The patent list is not exhaustive and is certainly not a substitute for a proper patent search . It should be noted that only U.S. Patents are included.

It should be noted that spelling, form and typographical errors in the original patents are preserved here.

Although his recognition as a registered patent agent permits him to represent others in all patent matters before the United States Patent and Trademark Office, Dr. Demchick limits his practice to patent matters involving inventions for which he is confident that his expertise will allow him to serve his client well. He will gladly discuss whether he is comfortable handling cases involving inventions in a particular field. He will err on the side of declining cases if he has uncertainty about his ability to do what is needed in the case. Dr. Demchick does not represent clients in court. However, he refers clients to a patent attorney who does represent others in court, if it appears likely that patent related representation in court is appropriate. Dr. Demchick prepares and files non-provisional (regular) patent applications and provisional patent applications. He prepares and files utility patent applications and design patent applications. He prepares and files U.S. patent applications and international patent applications under the Patent Cooperation Treaty (PCT). He prepares and files applications to enter the U.S. National Phase for inventions for which international patent applications (PCT) were already filed. One of the matters he discusses with each client or potential client is which type of application(s) best meets that client's needs. He usually does a patent search (patentability search) as part of the preparation of a patent application. He discusses the value of patent searching with each inventor before agreeing to prepare a patent application for that inventor.
