Spotlight on Safety
John Herber
Culture can be defined as a collective group of shared beliefs and values that shape how we act. We think of culture as it relates to the actions and reactions of a group, company, or society. However, it can also characterize an individual — what influences how you make day-to-day decisions or handle various situations. Personal process safety culture can be assessed by observing someone’s (yours or another person’s) response to situations involving a safety violation.

CEP: Patent Update - An On-Sale Bar to Patentability Can Arise in Various Ways

February
2014
Patent Update
M. Henry Heines
One of the ways in which companies often trip up in their attempts to develop a patent portfolio is by selling a product, or even offering it for sale, before filing a patent application. If more than a year passes between the date of a sale or offer and the application filing date, the application is disqualified from receiving a patent. Likewise, if a sale or offer a year before the filing date is revealed only after the patent has been granted, the patent is declared invalid. In either case, the applicant is barred from obtaining a patent, and this is known as an “on-sale bar.”
