There is NO court case against XF.
1. The whole thing has to be assessed under UK law.
The XF developers are UK residents under UK law.
They were employed by Jelsoft (VBulletin) under UK law.
They have set up XF under UK law.
2. Under UK law the skills and information in an employee's head belongs to them, after they leave the employ of a company.
Work belongs to the employer while someone works for them.
2A. When an employee leaves that employment they may be required to sign a non-competition contract. This can only last for one year.
That is, UK law supports the right of a worker to use their skills to work.
A non-competition contract can only cover a "reasonable period" which is normally taken as one year.
3. Xenforo website did not go live for slightly more than one year after their developers left IB (jelsoft/ Vbulletin).
That fits with a standard one year non-competition contract.
After that the XF developers were free to use their skills as they wished.
4. A UK court case cannot have been "filed" as IB has claimed.
A UK court case is public information unless subject to a special gagging order such as in cases of child abuse or terrorism. As public information its outline details are publicly available.
That means there would be an official listing with the XF and IB/ Jelsoft name on it. There is none.
4A. This is also borne out by the way the IB / Jelsoft announcement merely REQUESTS the XF team not to publish XF.
If there were a proper court case starting they would have an injunction to block XF from doing business. That would have a reference number.
Or they would have a case number and would obviously quote it to strengthen their statement - make it look legal.
No such numbers have been stated or leaked.
5. The most that can have happened is that IB has perhaps MADE APPLICATION to file a case.
Their application will be assessed by the UK legal authorities to see if it meets basic legal standards.
This takes weeks, for a complex case, months or years.
6. On the above points such an application does not meet legal requirements.
There will be no case.
