SVG & XPointer - When I write SVG code can I be sued?

It seems to me that anyone creating any but the most trivial Scalable Vector
Graphics, SVG, code may arguably be breaching a patent held by Sun
Microsystems. And therefore, in theory, would be open to being sued. I hope
that this email will elicit a definitive response from Sun that no such
danger exists - for me or for anyone else creating SVG code.
I am going to try to ask this question in as balanced a way as possible. Some
recipients will be aware that there has recently been an expression of
anxiety e.g. on the XML-DEV list regarding the implications of a Sun
Microsystems patent for the further development of XPointer. Some have gone
as far as to suggest that XPointer will be "DOA" as a result.
Hitherto I have seen no expressions of concern relating to the impact of
Sun's patent on the use of XPointer in SVG.
But when writing anything but the most trivial SVG code we cannot avoid using
"XPointer" syntax e.g. to access a filter using syntax along the lines of
"filter:url(#MySpot)" - the so-called "bare bones" XPointer syntax.
Some recipients may shrug and say "So what?". But there is a bizarre logic
that underlies the possibility of being sued for writing SVG code.
The W3C XPointer specification acknowledges the validity of a Sun patent.
Whether or not that is correctly acknowledged is a side issue at present. As
a consequence when anyone either "downloads" or "implements" XPointer ... as
we must when creating SVG ... we "agree" to provide Sun with our code no
later than the time we make that code available to anyone else.
So, in creating for example www.svgspider.com/Page05.svg which includes an
XPointer reference to a filter I have arguably breached Sun's patent and
theoretically, could be sued for doing so. Despite the fact that I did not
know of the "requirement".
At the time I posted that page I hadn't been made aware of the "legal"
requirement to notify Sun of my code. Am I now open to be sued?
The current wording of the XPointer Working Draft and the tacit (or perhaps
explicit) acknowledgement of the validity of Sun's patent seems to impose a
huge legal burden on anyone using SVG.
I am no lawyer but I understand that such conditions would be thrown out in a
UK or British Commonwealth court. But Sun might choose to sue me or anyone
else in, for example, a US court since ... given the World Wide Web ... my
"illegal" code can be viewed from there.
I don't want to overstate the danger. I hope that this email will elicit from
Sun and it's legal representatives a definitive statement that no danger of
being sued exists for those who "implement" XPointer by writing SVG code.
If SVG is soon to move forward to a Proposed Recommendation SVG developers
need to be sure that no cloud of legal uncertainty hangs over this matter.
I would value informed responses from recipients at Sun or at the W3C.
