If the subject material in the research paper is a patentable invention, it might also be the subject material of a patent.
The inventors of an invention may be the first applicants of a patent application. However, if they were employees, employed to invent as part of their normal duties for their employer, the employer is usually considered the first applicant for a patent application.
The rights in a patent or a patent application may be assigned to another person.
So: if there is a patent for an invention relating to the subject material of the research paper, it might be owned by someone other than the company from where the research paper originated. How did you check whether a patent or patent application exists for this subject matter?
Bear in mind that patent applications are made publicly accessible a certain time after the application for a patent is made. So, an applicant may have filed a patent application for the subject material of the research paper, and then published the research paper. The patent application - if extant - may not be publicly available yet. What this means is, if you put into practice the subject material of an unpublished patent application, you may in future receive notification of the patent application, and be advised to cease your operations. If the patent is granted, and you haven't ceased your working of the subject material, you might be liable for damages.
Bear in mind again, that there might be other patents - or patent applications - which relate to the subject material of the research paper. For some degree of certainty, you will need to do a patent search. You can do this yourself, but you have to bear in mind the warnings I gave above in relation to unpublished applications.
There are patent search firms who will do this service for you for a fee.
For a professional legal opinion, ask a patent attorney.
EDIT: If there are intellectual property rights to the subject material of the research paper, you can ask the proprietor of the rights for a licence.
