- Plaintiff’s Counsel: Ulbrich I.P., Ltd.
- Case Identification: 3:10-cv-00013, D. Minn., 09/29/2009
- Venue Allegations: Plaintiff alleges venue is proper in the District of Minnesota because Defendant is subject to personal jurisdiction, conducts business, and has committed alleged acts of infringement within the district.
- Core Dispute: Plaintiff alleges that Defendant’s Carryout™ portable satellite antenna product infringes a patent related to enclosed, transportable, and automated satellite antenna systems.
- Technical Context: The technology concerns self-contained, portable satellite television reception systems, primarily for the mobile market such as recreational vehicles, which automate the process of locating and locking onto a satellite signal.
- Key Procedural History: The patent-in-suit issued on September 29, 2009, the same day the complaint was filed. The complaint notes that on June 5, 2009, Plaintiff sent Defendant a letter enclosing the then-published patent application and providing notice that Defendant's product was allegedly covered by its claims, which Plaintiff asserts were indicated as allowable by the U.S. Patent and Trademark Office at that time. This pre-issuance notice forms the basis for Plaintiff's claims for provisional rights and willful infringement.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 7,595,764 - "Enclosed Mobile/Transportable Satellite Antenna System"
- Patent Identification: U.S. Patent No. 7,595,764, "Enclosed Mobile/Transportable Satellite Antenna System," issued September 29, 2009.
The Invention Explained
- Problem Addressed: The patent describes challenges with prior mobile satellite antenna systems, which were often cumbersome to mount on non-flat surfaces, required complex wiring, were awkward to transport, and needed to be set up or unfolded at each new location. (’764 Patent, col. 1:33-57).
- The Patented Solution: The invention is a self-contained satellite antenna system within a single, rigid enclosure that is designed for both manual transport and automated operation without requiring assembly, disassembly, or a change in its physical configuration. (’764 Patent, col. 1:59-col. 2:12). The system is intended to be immediately ready for use after being moved and placed in a new location, with the internal mechanisms for automatically finding a satellite signal. (’764 Patent, col. 5:53-64).
- Technical Importance: This approach seeks to provide the "ready-to-use" functionality of a permanently installed system with the portability of older, "suitcase-style" systems, but without the latter's time-consuming setup requirements. (’764 Patent, col. 1:50-57).
Key Claims at a Glance
- The complaint alleges infringement of "one or more of the claims" of the ’764 Patent without specifying particular claims (Compl. ¶10). The primary independent claim at the time of filing was Claim 1. A provided Inter Partes Reexamination Certificate (US 7,595,764 C1, issued Apr. 10, 2013) indicates that Claim 1 was subsequently cancelled. The analysis below pertains to Claim 1 as it was asserted in the complaint.
- Independent Claim 1 of the ’764 Patent recites:
- A generally rigid enclosure... defining a volume configured to enable both manual transportability of the satellite antenna system and automated operation of the satellite antenna system without a substantial change in the volume of the enclosure or manual repositioning of the satellite antenna system;
- The enclosure having disposed within its volume a satellite dish, a feedhorn, a low noise block converter, a motorized elevation drive system, a motorized azimuth drive system, and a control system to control automated operation.
III. The Accused Instrumentality
Product Identification
Defendant’s "Carryout™ portable satellite antenna product" (Compl. ¶9).
Functionality and Market Context
The complaint identifies the accused instrumentality by its trade name and general product category (Compl. ¶9). It does not provide any specific technical details regarding the Carryout™ product's design, components, method of operation, or market position. No probative visual evidence provided in complaint.
IV. Analysis of Infringement Allegations
The complaint does not provide sufficient detail for analysis of infringement. It makes a general allegation that the Carryout™ product infringes the ’764 Patent but does not include narrative allegations or a claim chart mapping specific features of the accused product to the elements of any asserted claim (Compl. ¶10). Therefore, a claim chart summary cannot be constructed from the provided complaint.
- Identified Points of Contention:
- Factual Questions: Given the lack of detail, a primary point of contention will be the factual question of the accused Carryout™ product's actual design and functionality. The dispute would depend on evidence establishing whether the accused product operates within an enclosure that enables both transport and automated use without requiring physical reconfiguration, and whether it contains the internal motorized and control components as recited in the asserted claims.
- Scope Questions: A central legal question would concern the scope of the claim phrase "without a substantial change in the volume of the enclosure or manual repositioning of the satellite antenna system." The court would need to determine if this language broadly covers any portable "all-in-one" system or if it is limited by more specific disclosures in the patent, such as the center of mass remaining the same during transport and operation (’764 Patent, col. 5:58-64).
V. Key Claim Terms for Construction
The Term: "a generally rigid enclosure... configured to enable both manual transportability... and automated operation... without a substantial change in the volume of the enclosure or manual repositioning of the satellite antenna system" (from Claim 1).
Context and Importance: This limitation, which appears in the preamble of Claim 1, encapsulates the core concept of the invention. The outcome of the infringement analysis for Claim 1 would have been highly dependent on the construction of this phrase, as it distinguishes the claimed invention from prior art that required assembly or unfolding.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification contrasts the invention with systems that "fold into a suitcase-like configuration for transportation," suggesting the key distinction is being ready-for-use immediately after transport (’764 Patent, col. 1:52-57). This may support a construction covering any portable system that does not require unfolding.
- Evidence for a Narrower Interpretation: The patent describes a specific embodiment where a handle is positioned such that the system is carried at an angle, yet the "center of mass of the system is the same when it is being carried as when it is being used" (’764 Patent, col. 5:41-44, 5:58-64). This could support a narrower construction requiring these specific physical and orientation characteristics.
The Term: "automated operation" (from Claim 1).
Context and Importance: This term defines the functional capability of the system once deployed. Practitioners may focus on this term because its scope determines the level of automaticity required to infringe.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The patent abstract states the system has a control system "to control automated operation," which could be interpreted broadly to mean any motorized control over the dish's position (’764 Patent, Abstract).
- Evidence for a Narrower Interpretation: An embodiment describes a control system that "operates to automatically position the satellite dish to acquire a satellite signal upon powering on the satellite antenna system" (’764 Patent, col. 9:5-10). This may support a narrower construction requiring fully automatic signal acquisition with minimal user input.
VI. Other Allegations
- Indirect Infringement: The complaint makes conclusory allegations of induced and contributory infringement but does not plead specific underlying facts, such as the existence or content of user manuals or instructions provided by the Defendant to its customers (Compl. ¶10).
- Willful Infringement: Plaintiff alleges willful infringement based on pre-suit knowledge. The complaint alleges that Defendant received a letter on June 8, 2009, which provided a copy of the published patent application and notice that its claims were allegedly allowable and covered the Carryout™ product (Compl. ¶¶19, 24). Plaintiff alleges Defendant continued its conduct despite this notice, which it argues constitutes an "objectively high likelihood that its actions would constitute infringement" (Compl. ¶27).
VII. Analyst’s Conclusion: Key Questions for the Case
The complaint, as filed, presented a dispute that would likely have turned on two central questions. The subsequent cancellation of the primary independent claim would have fundamentally altered the case, shifting focus to any surviving dependent claims. Based on the original complaint:
- A key evidentiary question would be one of factual characterization: what is the actual physical configuration and operational mode of the accused Carryout™ product? The complete absence of technical allegations in the complaint leaves this as the primary unknown upon which the infringement case would be built.
- A core issue would be one of definitional scope: how should the claim phrase "configured to enable both manual transportability... and automated operation... without a substantial change in the volume" be construed? The resolution would determine whether the patent covered a broad category of "ready-to-use" portable antennas or was limited to devices exhibiting the specific geometric and center-of-mass properties described in the patent's embodiments.
