Independent claims

What is actually asserted, verbatim.

Claim 1

1. An outdoor decorative solar powered lighting system, comprising: a flexible, elongated light string; an electrical wire extending through the light string and commensurate in length therewith; a plurality of sockets mounted on the light string and spaced evenly therealong; a plurality of light bulbs mounted to the sockets with one light bulb being mounted to each respective socket; a solar collector electrically connected to the light string and including a bottom side and an upper side; the solar collector including a housing and at least one solar panel supported in the housing for collecting radiant energy from the sun; a rechargeable battery contained within the housing and electrically connected to the solar panel for providing energy to the rechargeable battery; and a regulator switch electrically interconnected to the battery and the light string for automatically switching the light bulbs on and off whereby the switch is disposed to the open state from sunrise to sunset thereby preventing the light bulbs from lighting and the switch automatically going to the closed state upon sunset thereby closing the circuit and causing the light bulbs to light.

Abstract

An outdoor solar powered decorative lighting system includes a light string having a plurality of light bulbs evenly spaced along the length of the string and being electrically connected to a roof mounted solar collector having one or more solar panels or cells for collecting sunlight—radiant energy—from the sun and which is then conveyed to a rechargeable battery enclosed within the solar collector for discharge to provide the power to illuminate the light bulbs and thus create the decorative lighting effect with the solar collector including a switch to automatically turn the light bulbs on at dusk and to switch the light bulbs off at the following sunrise.

Named in one of these suits? A prior-art search is commissioned once and serves every defendant who shares it. The examiner's own search record is free on the tools page, and your first preliminary search is free — one claim, back within 24 hours — so you know whether there is art the Office never saw before anyone pays for more. Flat fees: $2,500$899 for the independent claims, $5,000$1,500 for every asserted claim.

This page is assembled from public records — federal court dockets and the patent's own file — and is updated as the case list changes. It states what the record shows and is not an opinion on the validity or infringement of any claim. Patent data via Google Patents; docket data via CourtListener.
