The appellant argues that Harbom does not disclose a
window frame assembly having a J-channel member integral with
the window frame, where the J-channel member contains integral

window frame and onto the underlying structure and then to

frame assembly to the house and also functions as a base upon
which the vinyl siding is secured proximate the window
(specification, page 4, lines 20-22 and page 5, line 1).

integral drains" to mean a structure like that seen as
