Opinion

Prost, Chief Judge.

*763 Appellant ChargePoint, Inc. appeals the decision of the U.S. District Court for the District of Maryland, which dismissed ChargePoint's complaint under Federal Rule of Civil Procedure 12(b)(6). The district court held that the eight patent claims asserted by ChargePoint were ineligible for patenting under 35 U.S.C. § 101 . We affirm.

The technology at issue in this patent infringement case pertains to charging stations for electric vehicles. The battery in an electric vehicle is recharged by connecting the vehicle to an electrical outlet. U.S. Patent No. 8,138,715 col. 1 ll. 20-24 ("the '715 patent"). At the time the patent application was filed, this process "typically require[d] hours and [was] often done overnight or while the electric vehicle [was] parked for a significant time." Id. col. 1 ll. 24-26.

Businesses such as restaurants, apartments, and shopping centers have installed electric vehicle charging stations for the convenience of their customers. These site hosts manage their charging stations in different ways. For example, a shopping center may prefer to offer free vehicle charging to its customers to encourage customers to continue shopping. Meanwhile, an apartment complex might limit access to its charging stations to ensure that only tenants can use those stations.

Utility companies have different concerns in mind. Generally, the supply of electricity available from a power grid may vary, and in some cases the grid may lack sufficient electricity to meet demand. Id. col. 1 ll. 39-41. During such periods when power supply is low compared to demand, supply to certain customers or services may be reduced based on a preplanned load prioritization scheme. Id. col. 1 ll. 44-47. The idea of reducing electricity consumption during periods of high demand is one form of what is referred to as "demand response." Id. col. 1 ll. 43-44. Demand response may also involve increasing demand during periods when demand is low compared to supply, by reducing the cost of electricity. Id. col. 1 ll. 47-50.

In addition to pulling electricity from a local electricity grid, electric vehicles may also supply electricity to the grid. Id. col. 1 ll. 58-61. This is referred to as vehicle-to-grid transfer or V2G. Id. Vehicle-to-grid transfer can be helpful during periods of high demand. Id. col. 1 ll. 64-66.

ChargePoint contends that its inventors created improved charging stations that address the various needs inherent in electric vehicle charging. This was accomplished by creating networked charging stations. According to ChargePoint, this network connectivity allows the stations to be managed from a central location, allows drivers to locate charging stations in advance, and allows all users to interact intelligently with the electricity grid.

ChargePoint alleged in its complaint that it was "the first company to propose networked [electric vehicle] charging infrastructure, in the face of widespread industry skepticism, and the first to patent networked [electric vehicle] charging technology." J.A. 83 ¶ 6. It further alleged that the asserted patents "describe a paradigm-shifting concept of how to charge electric vehicles in a dynamic, networked environment-a dramatic departure from the gas station-centric ideas that prevailed before ChargePoint's innovations." J.A. 84 ¶ 9.

According to ChargePoint, its inventions enabled individual charging stations to be *764 networked together to allow site hosts, drivers, and utility companies to communicate in real time to address the needs and preferences of each constituency. For example, the patents describe the ability to locate available charging stations remotely. See, e.g. , '715 patent col. 4 ll. 59-65. The patents also explain that the availability of electricity may be based on power grid data provided by a utility company. See, e.g. , id. col. 4 ll. 45-58. And the patents suggest that drivers can choose to transfer power from their vehicles to the power grid during periods of high demand. Id. col. 4 ll. 54-58. These capabilities are described in the four patents at issue in this appeal.

There are four patents at issue in this case: U.S. Patent Nos. 8,138,715 ; 8,432,131 ("the '131 patent") ; 8,450,967 ("the '967 patent") ; and 7,956,570 ("the '570 patent"). The patents share the same specification.

These patents generally describe electric vehicle charging stations that are connected to a network. The stations are connected to the local power grid, and electric vehicles connect to the stations by way of an electrical connector. '715 patent col. 5 ll. 38-42.

ChargePoint asserted claims 1 and 2 of the '715 patent in this case. J.A. 98-99 ¶¶ 49-50 (Compl.). These claims recite an apparatus that is controlled by a remote server, where the server controls whether electricity is flowing. Claim 2 adds a component that physically connects the charging station to an electric vehicle and that can activate or deactivate charging at the connection.

As for the '131 patent, ChargePoint asserted claims 1 and 8. J.A. 101-02 ¶¶ 60-61 (Compl.). Claim 1 specifies that the apparatus can modify electricity flow based on demand response communications received from the server.

With respect to the '967 patent, ChargePoint asserted claims 1 and 2. J.A. 104, 107 ¶¶ 71-72 (Compl.).
