"Loading status in a hypermedia browser having a limited available
display area"

I'm all for software patents, but this one looks sucky: show an
[animated] icon while data is loading. What else are you going to show?
In my opinion it should never have been patented because it's
extremely trivial and obvious to any developer. Long before 2002 I was
showing animated icons and images and progress bars while data was
loading (ironically within my Microsoft Access apps). Surely other
small-screen systems did the same thing? There had to be prior art,
even on other mobile devices.
The patent is very specific in its 42 claims, but several look to be
easy to overcome:
"3. A hypermedia browser as recited in claim 1, wherein the temporary
graphic clement indicates to a user that the browser is loading content."
Use the word 'Searching...' or 'Retrieving...'?
5. A hypermedia browser as recited in claim 1, wherein the temporary
graphic element is animated.
Show a static graphic with a numeric countdown?
Would altering Android trivially so it does 2 or 3 things differently
remove the infringement?
