Patent Registration of Gambhir Thoracostomy Forceps

Prehospital thoracostomy.

We read with interest the article on prehospital thoracostomy published in the journal [1] and the correspondence that followed recently [2,3].

This amounts to 9% of trauma patients attended in the same period. We are aware ...

A Predictive Model for Patent Registration Time Using Survival Analysis

Since a patent is an intellectual property to protect inventors’ exclusive rights of developed technologies, technological pre-occupancy is very important to the development of companies. For the technological pre-occupancy a patent registration time is surely important. In this paper we propose a predictiv...

The establishment of forceps-assisted delivery as ...
