Webinar: Patent research on retarders used in oil well cements

October 16th, 2013

Cementing is an important task in oil well completion. After the completion of drilling, a tubular body is introduced into the drilled wellbore, which is secured in the well by the process of primary cementing. In this process, the cement is placed in the annular space between the tubular body and wellbore, thereby forming a cement sheath to bond and support the tubular body and also to provide zonal isolation between the layers of wellbore. Retarders are generally used to extend the thickening time of cement slurry, thereby giving adequate time for proper placement of slurry in the annulus. Various types of retarders are used, depending upon the conditions of the wellbore. Retarder materials are mainly classified under lignosulfonates, cellulose derivatives, hydoxycarboxylic acids, organophosphates, inorganic compounds and synthetic polymers.

SciTech has conducted a study of patent literature in the area of retarders used in oil well cements. The study has identified the key patent filers as well as the different retarders that have been considered by them. The white space identification in the patent map created by SciTech can lead researchers to opportunities that are still unexplored.

USPTO and the Taiwan IP Office Establish a Patent Prosecution Highway Pilot

August 25th, 2011

Aug 22, 2011

The PPH will permit each office to benefit from work previously done by the other office.

The United States Patent and Trademark Office, as the designated representative of the American Institute in Taiwan, today announced a new pilot project for the Patent Prosecution Highway with the Taiwan Intellectual Property Office, as the designated representative of the Taipei Economic and Cultural Representative Office in the United States. The PPH will permit each office to benefit from work previously done by the other office, which reduces the examination workload and improves patent quality.

The expedited examination in each office allows applicants to obtain corresponding patents faster and more efficiently. Under the PPH pilot program, an Office of Second Filing (OSF) may utilize the search and examination results of an application filed in the Office of First Filing (OFF) in a corresponding application filed in the OSF.

Through PPH, an applicant receiving a ruling from the Taiwan Intellectual Property Office that at least one claim in an application is patentable may also request that the USPTO fast track the examination of corresponding claims in corresponding applications. Similarly, if the USPTO determines that at least one claim is patentable, the applicant may request accelerated processing of corresponding applications filed at the Taiwan Intellectual Property Office.

Full requirements for participation in each trial program at the USPTO can be found at http://www.uspto.gov/patents/init_events/pph/index.jsp. Information on the Taiwan Intellectual Property Office’s program may be found at http://www.tipo.gov.tw/pph.

The purpose of this trial program is to gauge the interest of applicants and determine if the program improves quality and efficiency and reduces the workload at the USPTO as well as the Taiwan Intellectual Property Office. The trial period will start on September 1, 2011, and is set to expire on August 31, 2012, but may be extended or terminated earlier depending on volume of activity and other factors. The offices will provide notice of any adjustment in the trial period.

PCT based National phase applications entry time in US

August 18th, 2011

The national phase entry of a PCT application is ought to be within either 30 or 31 months from the earliest filing or priority date associated with the PCT application (Article 22). As the legal parameters such as patent filing, enforcement etc., are under the jurisdiction of individual countries patents act, so is the case with selection of 30/31 months for national phase entry.

Patenting trends in Single Electron Transistor

November 15th, 2010

The single electron transistor (SET) is a type of switching device that uses controlled electron tunneling to amplify current. A SET is made from two tunnel junctions that share a common electrode. A tunnel junction consists of two pieces of metal separated by a very thin (~1 nm) insulator. The only way for electrons in one of the metal electrodes to travel to the other electrode is to tunnel through the insulator. Since tunneling is a discrete process, the electric charge that flows through the tunnel junction flows in multiples of e, the charge of a single electron. Applications of SET include nanoelectronics, GSI applications and low power applications. Find out more…

Patenting trends in Edible Packaging

November 15th, 2010

While edible packaging does reduce the burden on environment and brings down the costs arising out of recycling or reuse, it still has to meet expectations of the consumers in terms of appearance, taste, freshness shelf-life as well as receive regulatory approval. The most widely known applications of edible packaging are food wraps and casings. Find out more…

Pervaporation (PVP), a promising separation method, is an energy efficient way of separating liquid mixtures that form azeotropes with components of low relative volatilities and difficult to separate by conventional methods. PVP offers advantages over conventional techniques in terms of being less energy intensive and enabling modular configuration. PVP applications include removal of water from organics or vice versa and separation of organic/organic systems. Find out more…
