| From Tipple to TIPLO ... |
"For some, the promise of open source software is irresistible: it’s free; it’s built by passionate communities of developers and it facilitates constant innovation. For others, only proprietary software can offer the battle-tested quality and service-level support that businesses require, while at the same time rewarding creators of intellectual property.
For this event, we bring together two experts to engage in a provocative debate on open-source v proprietary software, in the congenial atmosphere of a TIPLO dinner".
Watchfully chaired by David Wilkinson (Head of IP, Stevens & Bolton LLP), the speakers are Keith Bergelt (Chief Executive Officer, Open Invention Network) and Anthony Finkelstein (Dean of Engineering Sciences & Professor of Software Systems Engineering, University College London).

While chasing a reader's inquiry regarding data exclusivity issues, this Kat found himself clicking through to a webpage with the descriptively helpful title "How to Calculate Standard Patent Expiry Dates and Data Exclusivity in Key Territories". Well, if that's what you feel like doing, this is the place where you can jolly well do it.
