What's wrong with the United Patent Litigation System (UPLS)?

What particular element of the United Patent Litigation System (UPLS) proposal has initiated concern regarding software patents?

The United Patent Litigation System (UPLS) is heavily inspired from the European Patent Litigation Agreement (EPLA). They have a lot of similarities, inside the FFII we call the UPLS the EU-EPLA, which is the EPLA rebranded with a EU flag on top to make it look like an EU project.

The UPLS and EPLA have in common that they are both international treaties, and not EU regulation (directive, council framework decision, etc…) per se. It means that other countries that are non-EU (such as Turkey, Iceland or even the United States) could potentially join the treaty. The fact that it is not an EU piece of law means that the legislator won't be the European Parliament. As we saw with other international treaties such as ACTA, those treaties are typically negotiated behind closed doors, and the Parliaments (the European one or the nationals ones) typically do not have a say over their content. The UPLS is mainly a piece of legislation written by bureaucrats of the Commission and Government officials, with no input whatsoever from members of those parliaments.

If software patents are enabled by the UPLS, what might be the effects on how computer programmers work? Please give examples

1. Near obligation of out-of court settlement for most of software producers: while large software companies has the means and the ability to defend themselves and go until the end of the court procedure, most of the european software players don't have the financial ressources nor the time to afford litigation in court. This is what we explained in the FFII's submission in July 2006 at the public hearing organised by the Commission on the consultation:

Aside from the software patents element, what is your perspective on the UPLS as a whole?

What advantages and disadvantages can you foresee if the UPLS is implemented?
